岩体工程具有加载和卸载两类不同性质的力学状态,在力学状态各异的情况下,节理岩体的力学特性有本质的区别。通过描述卸荷岩体的力学特性着重比较了卸荷岩体力学与常规岩体力学的不同之处。
Rock mass engineering has two kinds of mechanical states with different properties of loading and unloading. Under the condition of different mechanical states, the mechanical properties of the jointed rock mass are essentially different. By describing the mechanical properties of unloading rock mass, the difference between mechanics of unloading rock mass and that of conventional rock mass is emphatically compared.
