摘要

本文针对洞室

矿山边坡等一些工程的岩体应力变化状况

研究三轴卸载试验的应力路径

并提出以储备强度的概念进行资料整理

从而得出了轴、侧应力同时卸载下的岩石变形特性的特殊性.结果表明

用符合于岩体工程应力变化的加载路径来求取岩体的力学特性是十分必要的.

Abstract

A triaxial unloading experimental method fitting the process of stress changes in engineering practice such as underground openings or mine slope stability is proposed. The surplus strength with cleer for interpretation of data. It is found that through such a test there are unique features of deformation during simultaneous unloading of longitudinal and transverse stresses

which indicates that it would be necessary for mechanical properties of rock mass by using loading process coincident with the stress changes in geotechnical engineering.
