岩体结构面模拟方法探析

结合盐津桥水库右岸岩体结构面的实际情况,综合考虑结构面的几何特征和力学特征,针对不同类型的结构面,先运用蒙特卡洛（Monte-Carlo）方法获得随机结构面的几何参数,再利用有限元软件ANSYS对确定性结构面进行数值模拟,以获得有效的结构面模拟方法。此方法有效地解决了难以对数量多、尺寸小的随机节理进行逐条模拟的问题,又从变形和强度的弱化方面把节理考虑进去,与现实情况近似,是一种行之有效的方法。

Analysis of simulation method in rock mass discontinuities

By studying on rock mass discontinuities of Yanjinqiao Reservior right bank and analyzing discontinuity＇ s geometric and mechanics property, with different types of discontinuities, random discontinuity＇ s geometric parameters are obtained with the method of Monte - Carlo simulation and the certainty discontinuities are simulated with finite element software ANSYS to get effective method of discontinuity＇ s simulation. The method could be not only deal with a problem of large quantity and small site random discontinuity＇s simulation one by one, but also be considered with deformation and strength for weakening factor. The results are near to practical situation and this method is effective.
