    Opis:
    The paper deals with the assessment of slope stability on the road II / 595 near the village Zlatno. The assessment of slope stability was made before and after the landslide caused by floods in 2010. For proposal for a comprehensive assessment and possible remedial action is necessary to know the geological conditions and choose the appropriate method to assess slope stability. The calculation of factor of safety was made using GEO 5 software. The critical factors of safety have been determined by Petterson, Bishop and Sarma Methods. We analyzed possibilities to using these methods for assessment of slope stability. The Sarma Method is more appropriate for this calculation.

    Opis:
    The Kingdom of Bhutan is located in the eastern Himalayas approximately between latitudes 26° 41’52” N to 28° 14’ 52” N and longitudes 88° 44’ 54” E to 92° 41’ 7” E. The 38,686 square kilometers of landlocked and isolated mountain country has elevations ranging from about 160 meters in the southern part to more than 7500 meters in the northern part. People habituating along the steep slope valleys with river flowing at the foot of gorges are the finest epitome of exquisite scenery for outside world. However, such slopes particularly the unstable and loose ones pose greatest threat to the mankind and the development of the country. The complex arrangement of topography, constant tectonic movement and others human induced activities accelerate the landslide which are already active. The landslide problems in Bhutan dates back to 1960s when first road construction took place in the country. Every monsoon season is marked with countless landslide across the country, among which the landslide between Phuntsholing to Thimphu highway is the most frequent and disparaging. Many people lose their valuables and lives during the summer season every year due to landslides and falling stones on the highway. This research will help in bettering the knowledge in landslides and also combating it with necessary means. The main objective of this study is to comprehend the activating processes and mechanism of the landslide as well as examine to predict the possibility of another landslide by seeking natural causes and anthropogenic factors.

    Opis:
    Numerical modeling is an important tool to estimate slope stability. This publication shows application of a GEO 5 – slope stability software to evaluate stability of the “Łaski” Landslide in Międzybrodzie Bialskie. The slide surfaces, which were indentified in drill cores, were used to compute factors of safety (FS). The data from inclinometric measurements were used to verify the numerical model of the landslide. Calculations were carried out for three scenarios: first with normal water level, second scenario with lowered water level of 5 m and 10 m and the third scenario without water with the worst courses of sliding surfaces. As the result for each scenario the factors of safety were estimated. It was found that despite of water lowering and stabilization of existed surfaces, there is a considerable risk of a new sliding surfaces occurrence.

    Opis:
    In the northeast of Algeria, Souk Ahras area is known for the severity and spread of landslides, especially in Mechroha and Zaarouria municipalities. Stability analysis of landslides in these areas depends on the calculations of safety factor according to several parameters (physical, mechanical, geological…). The aim of this study is to investigate the parameters affecting the safety factor using the design of experiments (DOE) method, central composite design (CCD) and response surfaces methodology (RSM). These methods use parameter modeling and optimization to discuss a solution of landslide hazard by developing models of safety factor (Fs) considered as response. The other parameters adopted as input independent factors are geotechnical physical and mechanical parameters such as: the dry and wet unit weight (γd, γh), the water content (w), the plasticity and liquidity limits and the plasticity index (WL, WP, IP), the percentage of fine elements Ff (%) < 0.08 mm), the cohesion C and the internal friction angle (Phi). Obtained results show high correlations with a regression coefficient R2 of 0.88 and 0.93 in the two cases study and the predicted factor of safety model fit best to those obtained in the analytical and numerical modeling procedure. The final model is applicable to give reliable results on the safety factor of landslides.
