摘要
裂隙岩体中的渗流规律与传统多孔介质渗流规律存在本质的区别,裂隙岩体渗流具有不均匀性、各向异性和非连续性等特点,如何更好地刻画裂隙水渗流的这种特点是当前裂隙水数值模拟的热点与难点。介绍了裂隙岩体地下水渗流特性,对目前裂隙水渗流模型及其优缺点进行比较、分析,同时对主流数值计算方法和数值模拟软件进行概括介绍。
The permeability law of fissure water in bedrock is quite different to traditional porous media permeability law. The groundwater flow in fractured pluton is heterogenous, anisotropy and discontinuity, how to outline these characteristics is the keypoint and difficulty in the numerical simulation of fissure water. It is introduced that the groundwater permeating characteristics of the fractured pluton, analyzes the current fissure water permeating models, and introduces the numerical calculation methods and mainstream numerical simulation software.
