岩石力学试验,尤其是岩石的变形特征试验往往受试验机刚度的影响。为了真实地反映岩石的力学特性,笔者在采用平行刚性柱方法提高试验系统的有效刚度基础上,设计了圆盘劈裂刚性试验系统和载荷-位移测试记录系统,并对大理岩试件进行了圆盘劈裂初步研究,进而获得了大理岩圆盘劈裂应力-应变全过程曲线,同时对试验影响因素作了初步分析。
Rock mechanics tests, especially the tests of rock deformation characteristics, are often affected by the stiffness of the tester. In order to truly reflect the mechanical properties of the rock, the author designed a disk splitting rigidity test system and a load-displacement test recording system based on the parallel rigid column method to improve the effective stiffness of the test system. The preliminary study of disk splitting, and then obtained the whole process curve of splitting stress-strain of marble disk, and preliminary analysis of the influencing factors of the test.
