【Abstract】 According to the basic principle of soil mechanics for unsaturated soil,the stability of an actual expansive soils slope was analyzed with the shear strength considered as the variable with the deepness. The relationship between the center of slip surface and the safety factor k was obtained. The shallow character of the slip of expansive soils slope was validated. The failure rules were found and the reasonable gradient of the analyzed slope was put forward.更多还原
