摘要
岩体中存在的大量随机分布的裂隙对岩体的工程性质及稳定性有着极其重要的影响。传统的工程地质研究方法难以客观地描述其空间分布特征。应用概率与统计学的理论 ,通过统计分析得到裂隙的分布规律性 ,采用随机模拟的方法实现与统计分布相适应的裂隙网络是研究随机裂隙宏观特征的有效途径。通过模拟所得的 3D裂隙网络 。
Joints which randomly distributed in rock mass is the main factor affecting the rock mechanical property. Traditional engineering geology methods can not easily determine the joints' distribution rules in three-dimensions. Based on the statistics theory, the statistics rules of joints can be found out. Furthermore, by using Monte-Carlo method, it is easy to simulate the joints scattering in 3D rock mass. Then, according to the 3D network, the mechanical properties of rock mass such as conductivity and strength index can be determined. The 3D network also can be used for analyzing the stability of the random wedges of rock opening face.
