岩体内存在有许多直接看不到的隐微裂隙,其微小程度有时可达到只切割一个或半切割一个微小矿物颗粒。这些微小裂隙,直接影响着岩体的力学特性。因此,对岩体力学特性研究,不仅要从宏观上做大型岩体力学试验,也应从微观上将两者结合起来综合分析岩体的力学特性,这样将有利于宏观岩体力学性质指标的选择和工程处理措施的方案选择。笔者取霓石正长岩为试样,进行岩体力学试验。本文试图把宏观试验和微观观察结合起来研究岩体的力学特征。
There are many directly invisible hidden microcracks in the rock mass, which can sometimes be cut to a size of one or a half to cut a tiny mineral particle. These tiny cracks directly affect the mechanical properties of rock mass. Therefore, the study on the mechanical properties of rock mass not only needs to make large-scale mechanical tests of rock mass macroscopically, but also combine the two together to synthetically analyze the mechanical properties of rock mass. This will be of benefit to the selection of indexes of mechanical properties of macroscopic rock masses And engineering options to deal with the program. The authors take Aegirine as a sample, rock mechanics test. This paper attempts to combine the macroscopic test and microscopic observation to study the mechanical characteristics of rock mass.
