摘要
渗流作用对岩体强度的影响主要表现在渗水对岩体的物理化学作用和渗水对岩体的力学作用,并运用断裂力学理论详细推导出了存在孔隙水压力的岩体中裂纹初裂强度,其结果对评价渗流作用下工程岩体的稳定与破坏具有十分重要的意义。
The effect of seepage flow on rock mass strength display mainly the rock mass's physical degradation and chemical corrosion as well as mechannical property's change by seepage water. And the formulate for the initial rupture strength of the rock mass under hydraulic pressures are derivated in detail according to the theory of fracture mechanics.The results are very valuable for the assessment of the stability of engineering rock mass.
