近年来,研究工作者越来越重视岩石在静态和动态条件下基本力学性质的研究。其主要原因是,人们已经认识到与岩石有关的许多实际工程力学问题的解决,都有赖于弄清岩石的破坏机理、破坏准则、模型以及本构关系的建立。而研究这样一些岩石的力学性状,又必须研究岩石在各种围压、温度、应变速率等条件(即各种应力场与温度场)下的力学效应。 本文综合评述在这一领域中,国外研究者的一些主要研究结果。
In recent years, researchers have paid more and more attention to the study of basic mechanical properties of rocks under static and dynamic conditions. The main reason is that people have realized that solving many practical engineering mechanics problems related to rocks depends on clarifying the rock’s destruction mechanism, damage criteria, models, and the establishment of constitutive relations. To study the mechanical properties of such rocks, it is necessary to study the mechanical effects of rock under various confining pressures, temperatures, strain rates, and other conditions (ie, various stress fields and temperature fields). This article comprehensively reviews some of the major findings of foreign researchers in this field.
