摘要

地下洞室围岩稳定性研究是岩体力学重要的应用课题之一.由于岩体力学还是一门不很成熟的学科

还因为影响岩洞稳定的因素很多

对象复杂

目前要建立一种适合各种条件的理论和方法是很困难的.因此

在现阶段最好是把不同对象分类解决.对每类课题

抓住主要特征

做适当的简化

使之得到近似的解答.如能对工程的设计施工提出科学指导原则

也将是很有意义的. 影响岩洞稳定的主要因素有:a)地质因素(特别是岩体的地质结构特点);b)地应力因素;c)岩体基本力学性质;d)工程因素;e)地下水因素.其中特别是前面三项更为重要

本文将着重于这三方面的研究.

Abstract

This paper introduces comprehensive research on stability of a large –span cavern

including a lot of in –situ tests on rock

the measurements of initial stress field

applications of seismic velocity method and so on .Also it introduces numerical modeling with the finite element method .Finally

some significant conclusions for selecting the site and line of the large span cavern as well as for design and construction of the support are given .
