| 摘 要： | 岩体力学是研究现状的地质体受力条件改变时产生变形、破坏及其力学性质形成规律的科学。地质体与一般材料不同,由于其成因和经历的历史过程不同,致使其成分、结构及其形成条件不同。故现状的地质体当受力条件改变时,其力学作用,即变形和破坏机理亦不同。在进行岩体力学研究时,必须清楚地看到这一点。当前岩体力学研究成效不大的重要原因之一,就是没有注意地质体这一特点,在进行岩体力学研究时,不加分析地把地质体一律做为连续介质力学模型处理,显然是不合适的。

| Abstract: | Rock mass can be classified into(1)blocky faulted structure,(2)slabrent structure,(3)blocky jointed structure,(4)intact structure, and(5)loosened structure. On the basis of structure nature according to mechanical model rock mass can be divided into(1)blocky faulted system,(2)slabrent system(3)blocky jointed system,(4)intact system, and(5)loosened system. Rock mass structure is a geological foundation of rock mass mechanics. Mechanical model of rock mass is a mechanical foundation of rock mass mechanics. The structure mechanics of rock mass is a unity of both of geological and mechanical foundation, and it is an important aspect of the study of rock mass mechanics at pressent. |
