摘要

工程岩体中数量众多的裂隙面限制了离散裂隙网络模型在岩体渗流中的应用，迫使人们寻找能够用理论上成熟的等效连续介质模型替代，这就要求进行岩体多孔介质的水力等效性研究。在野外大量实测裂隙的基础上，进行裂隙密度、方位、大小、延续性、开度等几何参数的统计分析，以Enhanced Baecher模型建立离散裂隙网络随机模型，采用Monte-Carlo随机模拟方法进行三维裂隙网络随机模拟。在所生成的一定尺度的三维裂隙网络图基础上，给出计算研究域REV的方法，通过判断REV是否存在，确定能否用等效连续介质模型分析岩体渗流。

Abstract

The discrete fracture network model is confined in the application of rock mass seepage because of the numerous discontinuities in engineering rock mass. This makes investigators search mature equivalent continuum medium model in theory substitute the discrete fracture network model. Thus the research on porous medium hydraulic equivalence of fracture rock mass is necessary. Based on plenty of field measured fracture data

a statistical analysis about fracture density

azimuth

size

continuity

jaw opening is made

the random model of discrete fracture network is established on Enhanced Baecher model. The Monte Carlo random simulation is used in fracture network random simulation

thus the three-dimensional discrete fracture network figure of different dimension is obtained. On the basis of the three-dimensional discrete fracture network the REV is calculated

the equivalent continuum medium model can be analytical rock mass seepage.
