裂隙岩体三维随机裂隙建模与渗流数值仿真研究
Investigation on 3D modelling and seepage simulation of stochastic fractures for jointed rock masses
摘要
Abstract
Simulation of fractured rock mass is vitally important in the analysis of the stability of engineering rock mass.This study investigates the modelling approach and seepage simulation of three-dimensional fractured rock mass.To achieve the quantitative representation of its three-dimensional fractures in space,the attitude equations of three-dimensional fractures are derived based on the analytic geometry.Based on these,the algorithm of generating random fractures and a mesh partition strategy are developed,which provide the basis of fracture visualization and generating fracture cells.Especially,a treatment of three-dimensional intersected fractures is developed,such that the distortion of the cells is reduced.Furthermore,the seepage model of dual fracture-pore media is applied to simulate seepage in three-dimensional fractured rock mass.Different patterns of fractures and the mesh partition results are illustrated.Moreover,seepage characteristics of three-dimensional intersected fractures and random fracturs are analyzed.关键词
