Experimental studies of the “foundation-soil” system operation with sudden loading

Abstract

The experimental studies’ results of the foundations with a soil base interaction are presented. The relevance of the research is associated with increased accidents of buildings and structures in recent decades. The reasons for the occurrence and features of sudden foundations loading are considered. The experimental research methodology, the characteristic models of foundations are presented. The preliminary experimental studies’ results of the foundations with sudden loading are presented and analyzed. Some features of the “foundation-soil” system are determined. A decrease in the bearing capacity of the foundations during sudden loading, depending on the level and prestressing type, was revealed. It is established that the main reason for the decrease in the foundations’ bearing capacity is a change in the normal contact stresses diagram. The necessity and directions of further research in this area are substantiated.
