求翻译：另外，岩体是经构造作用和沉积成岩等多次形变和演化后而成为地质体的一部分，作为一种天然材料，通常包含着断层、挤压断裂带、软弱夹层及层面和节理裂隙等缺陷，在外界荷载和外界环境的作用(地应力或地震等)下，节理、裂隙进一步发展演化，最终会使岩体物理力学性质(变形模量和各种力学强度参数)劣化。损伤、损伤力学及其原理引人到岩体力学领域中，为研究岩体的损伤劣化过程和性质及解决目前一些岩体工程问题提供了理论，这是非常有意义的。是什么意思？

In addition, the rock is the geological part of the body after repeated deformation and evolution of tectonics and diagenesis, as a natural material, usually contains a fault, squeezing fault zone, the weak interlayer level and jointed defects in the role of the external load and the external enviro

In addition, the construct is rock and sediment into rock deformation and evolved more than once, after all, and become a part of the geology, as a natural material, and usually contain a slice, crush fracture, mezzanine and weak joints and cracks in the outer world and load and the outside world (i

Also, rock body is by constructed role and deposition into rock, times d
