Abstract

AbstractThe main purpose of the research is to study the parameters of strength and deformation of clay soil in triaxial compression conditions, under block cyclic loading. To date, there are no data on the results of studies under the specified loading regime. Experimental studies of the strength and deformability of clay soils of triaxial compression σ1 ≠ σ2 = σ3 under regime block cyclic loadings are carried out. A distinctive feature of the experimental studies is that they were conducted in triaxial compression prismatic devices with an aspect ratio of 100 × 100 × 200 mm. The results obtained consist in the study of vibration creep deformations and changes in the 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 alternating blocks with different values of the maximum load of the cycle.KeywordsStress-strainBlock cyclic loadingClay soils
