    Opis:
    The paper focuses on the problem of developing reliable geological models based on point data from boreholes and two-dimensional results of geophysical surveys with application of electrical resistivity tomography (ERT). The study area was the Morasko Hill in Poznañ (Poland), located within frontal moraines overlying Pliocene clays with a top surface strongly deformed glaciotectonically. Due to the presence of these deformations, the study area shows a complex geological structure. Analysis of archival boreholes indicates that the top surface of the Pliocene clays is extremely variable, hampering unequivocal determination of geological boundaries. ERT measurements were used to recognize the detailed geological structure of the area. Next, additional boreholes and CPTU soundings were made in selected localities characterized by anomalies in the distribution of electrical resistivity values. Following the drillings and soundings, and the results of the geophysical survey were reinterpreted. Such complex methodology of field work, including geophysical and geological surveys, has allowed us to present a reliable geological model of the area, in which the ERT results coincide with the drilling results. In practice, the preparation of an appropriate geological model, particularly in the vicinity of escarpments and slopes, is indispensable for designers of construction objects in the selection of foundations and analysis of slope stability.

    Opis:
    The paper discusses the problem of determining the thickness of a laterite cover using electrical resistivity tomography (ERT) in a selected area of the Seram Island in Indonesia. Seram Island lies in the tropical zone between the Seram and Banda seas. The laterite covers are rich in nickel, cobalt, iron and other metals. Concentrations of these metals in the laterites are high enough to form economic deposits. A significant part of the report concerns the measurement technique (ERT method) in difficult climatic (high humidity and temperature) and topographic conditions (equatorial jungle with significant variations in elevation) and the methods of processing and interpretation of the acquired data. The problem seems very interesting, because geophysical prospecting is currently more and more often conducted in poorly accessible regions of the world. Additionally, there are no sufficient and commonly available publications that would allow us to get acquainted with local measurement problems by potential contractors of similar geophysical investigations. The primary result of the geophysical survey was to determine the electrical resistivity of bedrock and laterite. This was the basis for the development of sections of electrical resistive distribution for the ERT profiles, which enabled to estimate the depth to the crystalline basement and the laterite thickness. It also facilitated to produce a map of laterite thickness, which may be an important material to develop the concept of searching and mining of nickel and cobalt ore.

    Opis:
    Geophysical research assists in clarifying the methodology of future building work. The geological structure in terms of lithological variation of Quaternary and older formations was identified in the area of the proposed garage near the ARENAobject in Krakow. In particular, the possibility of the presence of inserts of organic soils was determined. Ground Penetrating Radar (GPR) and Electrical Resistivity Tomography (ERT) were used for more complete and comprehensive recognition of the ground. As a result of the study of the subsurface, thin interbeds of weak bearing organic soils have been found just outside the outline of the planned building. It was found that the Quaternary formations which were identified by geophysical and geotechnical methods are an appropriate ground for direct foundation of the object.

    Opis:
    The study is focused on this part of the Dynów Foothiil, where many landslides are active. Extensive inventory work in the sites predisposed to development of landslides, initiated a search in order to improve traditional methods of mapping landslides. The traditional methods rely mainly on the analysis of topographic maps, geological and geomorphological mapping in the field. This article also descrobes the test of one of the modern methods of three-dimensional earth imaging – Airborne Laser Scanning. A major advantage of the method is the ability to filter out vegetation and other objects on the ground, which results in a precise terrain model. The relief inside the landslide consists of several secondary scarps and two lakes.The aim of the geophysical survey was primarily to interpret the geological structure of the landslides basement and the landslide body structure and to determine the depth of occurrence of the slide zone. It occurs at the shallowest depth in the upper part of the landslide, where Quaternary deposits are sliding down the slope of the surface of the top of variegated shales. The depth of slide surface increases significantly from the tectonic overthrust, where variegated shales are thrust on the hale-sandstone flysch layers of the Krosno Beds. In this part of the landslide, the slip surface can be at a depth of even 25 metres and is developed only within the flysch Krosno Beds.

    Opis:
    Correct determination of subgrade layers and properties is fundamental for later design and construction stages. Results obtained using traditional geotechnical tests are always of an overly specific nature - information is only provided in certain points in the field. Number of test points and the accuracy of results’ interpretation among them influence the design of an engineering structure foundation, which greatly impacts the cost of a project. Also, the lack of soil testing or insufficient investigation of soil conditions can be the reason for all kinds of legal claims from contractors which often exceed the whole investment budget by several or even several dozen percent. In order to prevent that situation new directives for geotechnical testing include additional geophysical methods such as electrical resistivity tomography (ERT) and ground penetrating radar (GPR). These non-invasive methods can give a spatial image and thus improve the accuracy of soil strata identification. However, these methods have also disadvantages and inaccuracies related to the measurement principles and interpretation of the results. This paper presents limitations and possible errors of geophysical methods ERT and GPR based on example tests carried out for road and railway engineering structures.

    Opis:
    The spring floods in 2010 and 2014 yr have caused many weaknesses and interrupts of embankments. Especially a flood from 2010 was the greatest cataclysm written down within a dozen or so years in Poland. Financial losses arising from her reason are huge and amount to a few billion zlotys. The considerable part of these losses is associated with flooding areas located in valleys of rivers as a result of the break flood banks. The embankments which were to protect floodplains in many cases did not fulfil their role. In the article results of geophysical investigation using electrical resistivity tomography of chosen fragments of flood banks from Warsaw and surroundings is presented. The research was conducted in two areas of Vistula river valley. The first area included the fragment of embankment alongWa³Miedzeszyñski street in the area of Fieldorf street (Warsaw district Goc³aw). The other fragment of flood bank was in surroundings of Dziekanowskie Lake in Warsaw suburb £omianki.

    Opis:
    The depletion of Zn-Pb ores in developed mining areas and the increase in metal prices have resulted in the need to search for new deposits which have not been exploited yet. A project of drilling new exploratory boreholes should be preceded by an interpretation of archival geological data. To obtain the most valuable information on the geological structure leading to its plausible interpretation, it seems to be purposeful and advisable to apply some geophysical methods that are reasonably cheap in comparison with others. The method of electrical resistivity tomography, which in this research uses two of many measurement protocols such as Schlumberger array and dipole-dipole array, is particularly useful. Computer interpretation of geophysical results allows a high resolution 2D and 3D geoelectrical model of rock mass to be created. The study was carried out using the multi-electrode Lund Imaging System manufactured by ABEM, Sweden. In order to evaluate the practical application of this method, Zawiercie Zn-Pb ore deposits were chosen as the area used in previous scientific research. Taking into account mineralization in its economic aspect, the deposits occur at relatively shallow depths of 50-120 m. In the investigated region, the Triassic carbonate formation overlays the Devonian rocks. The Keuper low-resistance clay, occurring on the surface, provides a very good electrical contact between an electrode and the soil. This is why there are favourable measurement conditions in this area. The boundaries between the Keuper, Devonian and Triassic formations are clearly noticeable in the resistivity cross-sections obtained. On the basis of the ERT results, it is possible to locate faulting zones as well as karst systems. One of the profiles clearly shows the occurrence of a low-resistance anomaly correlated with Zn-Pb mineralization, which was confirmed by borehole surveys. However, this early stage of the research with the use of the ERT method cannot unequivocally identify the ore body, particularly as it was conditioned by the limited depth of prospecting.

    Opis:
    This article presents the results obtained from geophysical measurements as a supplement to and refinement of geological information obtained from engineering geological studies for the newly constructed highways. The research was conducted using two geophysical methods: Ground Conductivity Meters (GCM) and Electrical Resistivity Tomography (ERT). The above measurements were made on three research fields located along the planned express road S-19 (Kraśnik-Janów Lubelski section). These areas were selected due to the large amount of available archival data and varied geological conditions. The publication focuses primarily on the presentation of the results obtained using the very fast and extremely efficient GCM method. By processing GCM data, using Laterally Constrained Inversion (LCI) and Spatially Constrained Inversion (SCI) algorithms, the values ofelectrical resistivity of the surveyed centers were derived. The results are presented in the form of cross-sections and maps of electrical resistivity from different depths, which were collated and compared with the results from another geophysical method, ERT. These examples show that the use of inversion has a significant impact on the refinement of geological boundaries between layers of different electrical resistivities. Thanks to the correlation of geophysical data with boreholes and engineering geological probes, detailed models of the geological structure of the analyzed areas were elaborated, which are necessary for the selection of appropriate solutions for the construction and modernization of road infrastructure.

Registered anomalies obtained from geophysical survey have been verified by geological and engineering tests (drillings and dynamic probing). Measurements were carried out along the part of the lateral earth dam, consisting of man-made soils with a thickness of approximately 7 m and underlying alluvial medium grained sands. The results obtained from the geophysical survey and direct assessment of density by means of dynamic probing allowed to demonstrate the relationship between a specific type of geophysical anomalies and the density of non-cohesive man-made soils.
