Title of the articleExperimental studies of deformation and physical-mechanical features of water-saturated clay soils under cyclic loading in bulk tray
Abstract.The article presents the results of experimental studies of deformation of water-saturated clay soils under cyclic loading carried in bulk tray in the laboratory of the Department of Soil bases, foundations, structural dynamics and engineering geology. When conducting experimental studies were conducted 5 test series. In each series of soils were tested cyclic loads of 400-500 cycles. As a test sample of soil was taken clay loam broken structure. Experiments were conducted in a test tray to the internal dimensions of 40?40?40 cm. The load on the ground surface transmitted through the rigid metal punch with a diameter of 16 cm. Performed an analysis the results of research, and set some of the behavior of clay soils under cyclic loading. Analysis of experimental results showed that cyclic loading has leads to an increase in the density and deformation modulus of soil, deformation under cyclic loading was damped character. In tests, the development of plastic deformation of soil attenuated in average closer to the 400-th cycle «loading-unloading», while in the process of cyclic loading of soil there was an increase of settlement deformations compared to the first cycle of loading up to 1,5 times.
Keywords.soil, cyclic loads, bulk tray, soil deformation, physical-mechanical features.
