State failure in soils under tension Mas·hyy Mhsvrknndhy Low

One of the key elements in soils Behavior Mas·hyy state breakdown Them. Experimental observations indicate that failure status in soils depends Mas·hyy Many factors such as stress Mhsvrknndh, density and stress path nbalshdh There. Most work conducted in this field stresses Mhsvrknndhy Moderate to high) often more than about kPa100 (is done. While Frmvlnvysy the dominant behavioral models based on the results, the Was. But the experimental results in too few low tensions Mhsvrknndhy In literature there. This study examines the empirical and theoretical Failure status in soils in tensions Mhsvrknndhy Mas·hyy low deals. Therefore Also important to collect experimental results, a set of triaxial tests Z·hkshyshdh Under low stresses Mhsvrknndhy) kPa10 to kPa200 (sand on Babolsar Has been done, and finally a number of behavioral models such as the famous Wong, CJS, Accreditation is Ld and Nova. Results from this study shows The first condition depends on nonlinear breakdown in soils Mas·hyy to tensions Mhsvrknndh has Mhsvrknndhy and tensions low, the intensity dependence Is more. Second, the failure condition for soils Mdlkrdn Mas·hyy, Equation is necessary in determining the breakdown level behavioral models, the effect of stresses Mhsvrknndhy Least be considered.
