节理岩质边坡变形的DDA模拟

Numerical simulation of deformation of jointed rock slope by discontinuous deformation analysis(DDA)

对原非连续变形分析方法(DDA方法)中边界约束方法进行了推广,将其应用于节理岩质边坡变形规律的数值模拟,并利用模型实验结果验证了推广方法的正确性。

The boundary restraint in the previous discontinuous deformation analysis(DDA)method was generalized and applied in the numerical simulation of the deformation in jointed rock slopes.The results of model tests has shown the validity of the present method.
