一、引言在研究岩石地压问题时,可以认为岩石是各向同性的,因为虽然每一晶体内方位不同其力学性质亦有改变,但是岩石内晶体排列是紊乱的,故以统计平均的眼光观之,可以认为是各向同性的;同时在岩石压力并不很大的情况下,它是具有弹性性质的。因此当研究地压问题时,可以把岩石作为均匀连续和各向同性的弹性体来处理。 I. INTRODUCTION Rock can be considered as isotropic when it comes to researching rockburst, because although the crystal orientation varies within each crystal, the crystal arrangement in the rock is disorganized, so the statistical average view It can be considered as isotropic, while it is elastic in the absence of rock stress. Therefore, when studying the problem of ground pressure, the rock can be treated as a uniformly continuous and isotropic elastomer.
