Title of the articleStudy of the time factor influence on the strength of clays
Abstract.When designing foundation base, the question arises about the mechanical characteristics of soils used in limit state calculations, especially if cyclic loading is considered as an external influence. At the same time, the “time” factor is not taken into account, that the structure is being built and operated for a long period. One of the ways to solve this issue can be to study the change in soil properties over time. The main purpose of this study is to identify the features of the change in the strength of clay soil samples under conditions of triaxial cyclic loading at different values of the exposure time in the desiccator before and during loading. The objectives of the study are to identify graphical dependencies and patterns of changes in soil strength over time and substantiate the results obtained. Results. Experimental studies were carried out on cylindrical samples made from soil of a disturbed structure. The main results of the studies performed are new data on the change in the strength of samples under triaxial loading depending on the loading mode, taking into account the time of "hold before testing" and "rest during testing". The analysis of the research results is carried out and some regularities of the behavior of clay soils under regime triaxial loading are established. Conclusions. Establishing the influence of time on the change in the values of limiting vertical stresses in a sample of clay soil of a disturbed structure under conditions of triaxial compression is an important task in the construction industry.
Keywords.clay soil, two-stage loading, time, hardening, triaxial compression
