Abstract:
This work aimed to study the physical and mechanical parameters which influence the deformation of improved Loess slope. Using the collapsible loess taken from Shanxi Taiyuan as the object of study, direct shear test was carried out, cohesion and the internal friction angle of improved loess were obtained under different water contents; and then based on the testing data, the finite element software ABAQUS was used to discuss the effect of different moisture content, elastic modulus and Poisson's ratio on slope deformation. The result of the study showed that: The solidified agent SH could improve the shear strength of loess; The water content had great effect on deformation of improved loess slope, Poisson ratio had almost no effect on deformation of improved loess slope. The research results provide certain reference value for the promotion of solidified agent SH in the loess area, and also give theoretical references for the design and management of the actual slope engineering.
