Impact assessment of tissue suction, saturation, and relative density on the shear strength and behavior Mechanical Mas·hyy Rsdar unsaturated soils

In this article the laboratory study of the suction effect of tissue, degree of saturation And relative density on the shear resistance and mechanical behavior of soil type Mas·hyy Rsdar discussed. Therefore, tests in two modes completely S·hmhvry Saturated and unsaturated used. Saturation tests in two modes Consolidation Z·hkshyshdh findings and strengthen the findings in two groups with densities Z·hkshynshdh The relative strengthening of the tensions affecting 50, 100 and 200 do Kylvpaskal Are. Apparatus for testing unsaturated unsaturated S·hmhvry Built in Tarbiat Modarres University is used. S·hmhvry experiments Thkymyafth unsaturated form with a fixed amount of water) CW (in two groups The relative densities of different amounts of suction in the primary tissue 30, 100 150 Kylvpaskal the effective consolidation stresses 50, 100 and 200 Kylvpaskal Been done. Suction for measuring tissue volume change and water phases Weather Hfrhyy soil displacement method and the central cell unsaturated double Used. Based on results of tissue suction effect, Saturation, relative density and strengthening on the tensions and the volume changes Pressure weather Hfrhyy soil samples were studied. More behavior Using soil mechanical stress state variables in unsaturated soils Rupture parameters of soil shear Mtalhshdh study were calculated.
