摘要

所有岩体

特别是软弱岩体

在一定载荷的长期作用下

都具有变形随时间增长而影响其强度的流变特性.这一点

早被许多学者的研究结果及岩体工程实践所证实. 众所周知

断层破碎带、软弱夹层以及被松软物质充填的各种结构面(以下统称弱层)的流变性质更为显著.弱层是许多工程基岩或围岩经常碰到的.因此

对弱层流变特性及其对强度的时间效应的研究

从理论和实践上都有重要的意义.

Abstract

Based on the in-situ uniaxial compression rheological tests on the weak intercalations and on the fault fragmentation zone

time-effect on deformation and failure mechanism of the weak rock mass is investigted. The method of determining long-term strength of weak intercalations

empirical formula and influencing range of the time-effect on the various tests are made and the met of determining different stages of rheological process and long-term strength are discussed in detail .
