Title of the articleBearing capacity of foundations base under combined, alternating, long-term static and cyclic loading
Abstract.Problem statement. The existing bearing capacity and deformations calculation methods are mainly designed for short-term static or cyclic loading with taking into account that the load data is constant for the entire period of the building or structure construction and operation, which calculations are not able to take into account the base of foundations deformation features under a successive alternation of long static and cyclic loads. The purpose of the study is improvement the bearing capacity analytical calculation method with taking into account changes in the clay grounds deformation and strength properties in conditions of a triaxial stress state under combined alternating long-term static and cyclic loading. Results. Based on the results of experimental studies, graphical and analytical forms for described the results of changes in the initial and transformed clay grounds deformation diagrams under combined alternating cyclic and long-term static loads, the ground strength and deformation properties. Conclusions. The significance of the results obtained for the construction industry is in the developed equation ultimate bearing capacity equation for combined alternating static and cyclic loads, which take into account the simultaneous change in the ground rheological and strength characteristics, the hardening process, and loading regimes.
Keywords.triaxial compression, clay ground, static loading, cyclic loading, combined loading, bearing capacity, transformed diagram, strength, specific cohesion, hardening.
