Title of the articleStrength and deformation of clay soils in the conditions of the triaxial compression under block regime cyclic loading
Abstract.Problem statement. The main goal of the performed studies is to study the parameters of strength and deformation of clay soil under conditions of triaxial compression under block regime cyclic loading. To date, there is no data on the results of studies under this loading regime. Results. Experimental studies of the strength and deformability of clay soils of a triaxial compression ?1 ? ?2 = ?3 under block regime cyclic loading are carried out. A distinctive feature of experimental studies is that they are performed in three-axis prismatic compression devices with a 100?100?200 mm aspect ratio. Regularities of changes in the main soil characteristics during transitions to blocks of high and low stress levels have been established. New data are obtained on the regularities of deformation of clay soils under regime block cyclic loading. Conclusions. The significance of the results obtained for the construction industry is to investigate the deformations of vibration creep and the changes in fatigue resistance to the destruction of clay soils under triaxial regime block cyclic loading. It is established that the stress-strain state, deformations and fatigue strength of soils vary depending on the sequence of alternation of blocks with different values of the maximum load of the cycle.
Keywords.block regime cyclic loading, clay soil, triaxial compression.
