在采矿和类似的挖掘工程中必须暴露出大面积岩层,于是引起岩层弯曲和离层。这种破坏可解释为主要受张力破坏。有代表性的例子是在良好支护巷道中产生的底鼓现象。测量岩层的抗张强度作为岩石力学领域内研究工作(如岩层控制模型试验)和一般
A large area of rock must be exposed in mining and similar excavations, causing the rock to bend and delaminate. This destruction can be interpreted as being mainly ruptured by tension. A typical example is the kick-drum phenomenon that occurs in well-supported tunnels. Measurement of rock tensile strength as a field of rock mechanics research (such as rock control model tests) and general
