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。通过证实 ,本文所建立的公式具有较高的可靠性 ,可用于暴雨入渗边坡等实际的工程岩体稳定性评价。
This paper applied the theory of fracture mechanics to guantitatively analyse the influence of the fissure length, direction and interval on the rock strength and to derive, in detail, the formula of the initial rupture strength of the fiasure water bearing and confined Rockmass. Trials show that the formula proposed in this paper has a higher reliablity and can be used to evaluate the stability of the practical engineering rock mass such as the versant (side slope) permeated by the torrential rain, etc.
