数值流形元中水压力与开挖作用的模拟方法研究
Water pressure and excavation simulation with the numerical manifold method
摘要
Abstract
Water pressure is an active factor affecting the security of geotechnical engineering. Excavation is common load in rock and soil engineering. As a new developed numerical method, the simulation of water pressure and excavation with Numerical Manifold Method (NMM) is seldom examined. We give the equations to compute the effects of three different types of water pressure acting on joints. Simulation of excavation by removing the blocks and elements in the region to be excavated is easy to describe and the principle is clear. This method is commonly used in numerical methods. The example shows that after introducing this method to NMM, the NMM can simulate the trend of deformation of surrounding rock after excavation. This work extendes the usage scope of NMM in geotechnical engineering.关键词
