一岩石力学性质自然界广泛存在的构造形迹,是地应力作用的结果.然而,室内岩石力学实验和野外地质现象表明,在同样形式的应力场中不同性质的(力学的、化学的、矿物的)岩层、岩体和地块,在构造方面的反映是不一样的;同样大小、同一方式的应力和加之于不同性质的地块上所产生的构造现象和构造特点可以完全不同.例如,一个地区受水平压力时,有些软弱的地层发生褶皱,而另一些坚硬的地层则发生破裂和矿物相变.这样即可得出,力的作用方式和被作用岩体的性质,是两个主要的因素.两者结合起来才产生某种构造现象.所以,在考虑地壳形变时,需要把这两个因素同时并重的加以考虑和分析才能从本质上掌握各种构造形迹的形
A rock mechanics nature The structural traces that exist widely in nature are the result of geostress. However, indoor rock mechanics experiments and field geological phenomena indicate different properties (mechanical, chemical, mineral) in the same form of stress field. The rock formations, rock masses, and land masses are different in their tectonic reflections; the same size, the same type of stress, and the tectonic phenomena and structural features produced on different types of land can be completely different. For example, a region Under horizontal pressure, some weak formations are wrinkled, while other hard formations are subject to rupture and mineral phase transformation. It can be concluded that the mode of action of the force and the nature of the rock mass affected are the two main factors. The combination of the two results in some structural phenomenon. Therefore, when considering the deformation of the earth’s crust, these two factors need to be considered and analyzed at the same time in order to fundamentally grasp the shape of various structural traces.
