Abstract

One of the main issues in the design of bases and foundations on water-saturated soils in conditions of possible seismic impacts is the geotechnical substantiation of the possibil-ity of construction. Among the main influencing factors, one can single out the assessment of the ability of water-saturated sandy soil to resist vibration liquefaction. The paper presents the re-sults of studying the behavior of sandy soil samples under conditions of triaxial cyclic loading, which is equivalent in strength to seismic action. The urgency of the problem lies in the study of the process of vibration liquefaction with an assessment of the deformability of water-saturated soils under dynamic influences. The tests were carried out in a pneumatic stabilometer. A special technique has been developed that provides for the imposition of dynamic stresses on the static stress state of the samples. The criteria for vibration liquefaction have been determined. A ge-otechnical substantiation of the possibility of building a stadium on water-saturated sandy soils under conditions of seismic loading has been carried out. The parameters of the earthquake, in which the soils will show liquefaction, have been established.
