Opis:: The paper presents an assessment of the suitability of a laboratory vane apparatus, a cone penetrometer as well as a shear vane tester and a pocket penetrometer for determination of the parameters of the undrained shear strength of fly ash from the Power Plant “Skawina”. The suitability of the cone penetrometer and the laboratory vane apparatus for the determination of the undrained shear strength of the fly ash has been shown. On the bases of the obtained test results, , drained and undrained shear strengths of the subsoil made of the fly ash under the square pad foundation were calculated according to Eurocode 7. The calculations of the ultimate resistance of the drained subsoil showed that it was several times bigger than its value in undrained conditions. This confirms the need for the proper determination of the angle of internal friction and cohesion as well as the undrained shear strength of fly ashes.

Opis:: The paper contains the designs of modifications of testing devices, which were constructed for the purpose of checking the functional properties of the mechanical pallet fixing lock built by the KOMA – Industry s.r.o. company, which is used for securing pallets with cars in parking houses. The individual testing devices consist of one or two positioning devices, the moveable parts of which are placed perpendicular to each other in the frame of the testing device. A mechanical pallet fixing lock is attached to the moving part of the perpendicular positioning device, and it consists of the following three parts: the body, the pulley holder and a compression coil spring. A plate is attached to the moveable part of the horizontal positioning device and is adapted to receive a pressure force sensor or to engage a mechanical fixation lock or the break of an electromagnetic locking device. The paper contains the description and method of experimentally determined resistance, which is created by the shear friction on contact surface, when inserting or withdrawing the pulley holder tube from the plain bushing of the fixation lock body. Additionally, the paper provides the values of the measured vertical forces, which are generated by the deformed compression spring with a wire of circular cross-section during inserting/withdrawing of the pulley holder tube into/from the fixation lock body. The values obtained from the performed experimental measuring of vertical forces and frictional resistance during the inserting of the pulley holder tube into the plain bushing of the fixation lock body will be used for subsequent checking of the functional properties of pallet fixation locks and will allow determining the optimal position for attaching the pallet fixation locks to stack cell steel beams in the parking house, on which chain conveyers push pallets with cars are parked.

Opis:: Authors analyze the resistance of shear and compression of the Polish Baltic soils on the depth of 10 and 20 m below the sea bottom. On the basis of selected mechanical properties of the Polish Baltic soils have been characterized the devided geological-engineering units on the depth of 10 and 20 m below the sea bottom. These characteristics concern the engineering- geological division of the sea bottom are founded on the detailed analyses of the geological maps of the Baltic Sea bottom in scale of 1: 200 000 and on the geological interpretation of seismoacoustic investigations which were executed in selected parts of the area of the Baltic Sea and also on the base of the results of detailed engineering-geological research of some fragments of the sea bottom and the coastal zone in the area of western Pomerania. On this base, the authors present the engineering-geological units of the Polish Baltic soils on the depth of 10 and 20 m below the sea bottom. There were taken into account certain geological criteria such as a lithological type, genesis and age of deposits and also geotechnical criteria beside of resistane of shear (f) and resistance of compression (Rc), the next properties such as a index of density (ID ), index of liquidity (IL ), angle of internal friction (), cohesion (c).
