摘要

A discontinuous deformation and displacement (DDD) analysis method is proposed for modellingrnthe rock failure process. This method combines the rock failure process analysis (RFPA) method (basedrnon finite element method) and discontinuous deformation analysis (DDA) method. RFPA is used to simulaterncrack initiation, propagation and coalescence processes of rock during the small deformation state. The DDArnmethod is used to simulate the movement of blocks created by the multiple cracks modelled by the RFPA.rnThe newly developed DDD method is particularly suitable for modelling both crack propagation and blockrnmovement during the rock failure process because of the natural and convenient coupling of continuous anddiscontinuousrndeformation analyses. The proposed method has been used to simulate crack initiation, propagationrnand coalescence within a slope as well as the block movement during the landslide process. Numericalrnmodelling results indicate that the proposed DDD method can automatically simulate crack propagation andrnblock movement during the rock failure process without degrading accuracy.
