Stability Analysis of Unsaturated Soil Slopes Reinforced With Retaining Wall

The retaining wall commonly existing in slope engineering, the effects of matric suction and retaining wall are important in the design and safety evaluation of the reinforced slopes. In order to decrease the occurrence of failure it is essential to properly evaluate the global stability of unsaturated soil slope reinforced with retaining wall. By using the strength reduction finite element program to implement considering matric suction, the global stability of reinforced slope is analyzed; and the computational results reveal the contribution of matric suction and indicate the variation trend of global potential sliding surface. Sensitivity analysis of suction friction angle is also presented.
