【摘要】 岩体的力学作用和力学性质明显地受岩体结构、岩性及岩体赋存条件,特别是地应力控制着。因此,根据岩体结构、岩性及地应力对岩体中应力传播、岩体变形及破坏所具有的力学效应特点,可将岩体分为块裂介质、碎裂介质及连续介质等三种力学介质。岩体力学是由块裂介质岩体力学、碎裂介质岩体力学及连续介质岩体力学共同组成的力学体系。更多还原

【Abstract】 The mechanical behaviour and properties of a rock mass are obviously determined by its structure, lithology and its occurrence, and especially by the ground stress. According to the mechanical effects of the above-mentioned factors to the stress propagation, deformation and failure of the rock mass, the rock mass may be classified into three types of mechanical media, i.e. the faulted, jointed and continuous media.Rock mass mechanics is a mechanical system consisting of three parts: rock mass mechanics of a faulted medium, that of a jointed medium and that of a continuous medium.更多还原
