基于PFC3D的山地造型方法

Research on Mountain Surface Shape Modeling Method based on PFC3D

为了研究山区发生地震、滑坡、泥石流、崩塌等自然灾害后岩体破坏程度及灾害影响范围,使用模拟手段进行分析.使用PFC3D中的三角形面构建了水平尺寸100 m×100 m的山地表面,使用MATLAB处理了一些构造过程中的问题.模拟表明,该方法构造了型如MATLAB中peak的形状,形成山峰表面形状的效率较高.该方法可为使用PFC3D进行复杂山地模拟而进行山地造型的问题提供一种可行的,工作量相对较小的方法.

In order to study rock mass damage and disaster influence scope after natural disasters such as earthquake, landslide, debris flow and collapse, simulation methods are used due to the complexity of its action. A 100 ×100 m2 of the mountain surface is constructed using PFC3D triangle surface, and MATLAB is employ to deal with some problems in the process of construction. Simulation show that the proposed method can construct the model such as the shape of the peak in MATLAB, and the formation of mountain surface has a high efficiency. The method can be used to model complex mountainous simulation, and it is feasible with relatively small workload.
