在不连续岩体中发生三维岩质边坡倾倒。为了在三维空间内模拟岩石接触大位移破坏过程并研究其破坏机理，发展了一种新的离散数值方法--三维非连续变形分析（DDA）。本文首先介绍了基本原理，然后详细推导了公式。最后，以边坡破坏模拟为例，验证了该方法在岩质边坡破坏研究中的适用性。数值模拟结果表明了该方法在研究三维岩质边坡破坏机理方面的优越性。
A three-dimensional (3D) rock slope toppling occurred in a discontinuous rock mass. To simulate the failure process and study the mechanism of this rock failure with contact and large displacement in 3D, a new discrete numerical method has been developed called the 3D discontinuous deformation analysis (DDA). This article first introduces the basic principles and then derives the formulas in detail. Finally, the slope failure simulation is applied as an example to investigate the applicability of this new method to rock slope failure research. The simulation results indicate the advantages of using this new method to study the mechanism of a rock slope failure with 3D behavior.
