| 摘 要： | 本文以复合岩石的压缩试验为基础,讨论了复合岩石在不同粘结状态下的各种压缩力学特征。作者发现:所有复合岩石的力学特性都与层间粘结强度有关,并随其改变而不同。复合岩石的极限强度、弹性模量和破坏能量都随着层间粘结强度的增加而增大,到一定值后逐渐稳定下来,而复合岩石的泊松比随层间粘结强度的增加而减小。

| Abstract: | In this paper, on the basis of the compressive tests of composte rock, the different kinds of mechanical properties of composite rock under different bond states are discussed. Authers found that all mechanical properties of composite rock relate to the bond strength between layers and are dilferent when the layers' bond strength is changed. With increasing the bond strength between layers of the composite rock, the limiting strength, elastic modulus, and breaking energy increase, and this phenomenon is to be stability gradually when they reach some volue, with increasing the layers' bond strength, the poson ratio reduces. |
