摘要
运用断裂力学理论定量地分析了裂隙长度、方向、间距对岩石强度的影响 ,详细推导了含裂隙水压力岩体的初始开裂强度公式。通过有关试验结果证实 ,所建立的公式具有较高的可靠性 。
This paper applied the theory of fracture mechanics to quantitatively analyse the influence of the length, direction and internal of cracks on the rock strength. And the formulae for the initial rupture strength of the rock mass under hydraulic pressures are also derivated in detail. The result has verified that the formulae proposed in this paper is highly reliable in the assessment of the stability of engineering rockmass and rock slope with water inbiltrated due to torrential rain.
