【 摘 要 】

Regarding numerical calculation convergence and plastic zone through the slope as the criterion of slope instability, strength reduction method as calculating principle, the stability of soil slope was analyzed by using finite element software ABAQUS, and on the basis of analysis, the best position and pile distance of anti-slide pile of reinforced soil slope were studied. The numerical results showed that with the increasing of distance between anti-slide pile and toe position, safety coefficient raised firstly and then decreased, when the ratio between the horizontal distance of anti-slide to slope toe and horizontal distance of slope is around 0.6, which is the largest safety factor; The pile spacing had certain influence on the soil slope safety factor, with the different pile spacing, the safety factor was different. With the increase of the pile spacing, the safety factor decreased gradually.
