节理岩体的有限元模拟研究综述

本文综合阐述了对于节理岩体进行有限元模拟所用的两种方法,即采用特殊的节理单元或者运用等效模拟的方法。阐述了常用的节理单元的发展,并介绍了基于等效模拟思想的节理岩体复合本构模型,其中典型是均匀节理单元。最后指出,可以把研究重点放在均匀节理岩体的推广与应用上。

Summarization on Finite Element Simulation Research for Jointed Rock Masses

This paper describes two methods of finite element simulation research for jointed rock masses synthetically, i.e. , adopting the special joint elements or employing the method of equivalent simulation. Development of the conventional joint elements is expatiated. This paper also introduces the complex constitution models for jointed rock masses based on thinking of the equivalent simulation, in which homogenized joint element is typical. It is pointed out that the research emphasis can be put on the generalization and application of homogenized joint element at the end of the paper.
