ABSTRACT

In modern conditions the soils base of buildings and structures are exposed to various types of regime cyclic loading. Existing calculation methods for foundations bearing capacity and deformations are developed mainly for the case of short-term single static load or cyclic loading with constant parameters during the whole period of exploitation. Buildings and structures for various purposes and their soil bases, along with cyclic loading with constant parameters, are subjected to cyclic loading of non-stationary regimes which are usually reduced to block loading for calculations and in some cases these loads are the main ones determining the safety of buildings and structures as a whole. Influence of cyclic loading of non-stationary regimes on the behavior of soil foundations is practically unstudied. In this connection researches have been conducted and methods of calculation of bearing capacity and settlement of foundations on clayey soils at regime block cyclic loading have been developed.
