Title of the articleExperimental studies of the stress-strain state of the three-layer soil base under short-term plate-bearing test and the presence of the water saturated layer
Abstract.Problem statement. The purpose of the study is to reveal the effect of water saturated layer to stress-strain state of a layered subsoil base of the slab foundation. Result. The main results of the study consist in obtaining a picture of deformation for layered subsoil base in the presence of water saturated layer with an underlain by a waterproof layer. Compressive stress distribution diagrams in the horizontal plane of each layer of layered subsoil base and in the vertical plane in depth are obtained. Direction of a vertical filtration water in the subsoil base are determined. Conclusions. The significance of the results obtained for the construction area is to establish the influence water saturated layers on inhomogeneous stress-strain state that changing in the all of volume in the process of loading. Pore water influences to stress-strain state all of multilayered base including overlying layers of the soil, increases capillary pressure, causes deformation of form change.
Keywords.slab foundation, water saturated subsoil bas, stress-strain state.
