关于岩石K_(IC)和J_(IC)的测定及其与岩石地质特点关系的研究

THE K_(IC) AND J_(IC) MEASU REMENT FOR ROCKSAND THE INFLUENCE OF GJOLOGICAL FACTORSON K_(IC_ AND J_(IC)

本文介绍了测定岩石K_(1C)和J_(1C)的方法及设备。提供了混合斑状花岗岩、斜长混合花岗岩等测试结果。并对试验中的疑难问题做了初步论述。另外,关于岩石结构和构造以及微裂隙对岩石断裂韧度K_(IC)和J_(1C)的影响,也作了初步的探讨。

In this paper, the method and test facility used for measuring KIC and JIC of rocks are introduced.The results of measurement conducted on migmatitic granite and porphyritic granite specimens are shown, and some knotty problems concerning the tests are discussed tentatively. Furthermore, the influence of the texture and structure and microcracks of rocks on the KIC and JIC the fracture toughness is inquired.
