Abstract

TSZ-6A type strain control triaxial compression apparatus is applied for indoor test of some soil samples in Gansu Longdong (Qingyang) loess landslide, unconfined shear test of undisturbed soil samples, and the loading and unloading test of loess remodeling. The influences of different moisture content and confining pressure and the initial stress field on loess strength are considered respectively. Mechanical properties of loess in the state of loading and unloading state are compared and the corresponding q- curves are drawn. The test shows that loess strength has a lot of structural characteristics, and loess structural damage has great impact on its strength. At the same time, the loess strength has important connection with its moisture content, stress state and stress path.
