摘要:
岩石边坡的破坏模式和稳定性受岩体结构控制,对开挖边坡而言,在确定的边坡几何条件下,边坡可能具有多种破坏模式。不同破坏模式下边坡的稳定性系数不同,对稳定性系数不满足安全要求时需对边坡采取加固措施。对门家山软岩边坡而言,可能发生的破坏模式有平面型、楔型和圆弧型,根据稳定性系数计算结果,平面型稳定性系数最低,其余两种模式稳定性系数均能满足安全要求,但圆弧型破坏模式的稳定性系数偏低,故建议针对两种破坏模式采取针对性加固措施。
Abstract:
The failure modes and stability of rock slope are controlled by rock mass structure.For excavation slope,there are multiple destruction modes under the conditions of specified slope geometric.The stability coefficients of the slope are different in different destruction modes, and reinforcement measures for slopes should be taken when the stability coefficient doesn’t meet the safety requirements.For soft rock slope of Mount Menjia, there are three possible slop failure modes such as plane type, wedge type and arc type.According to the results of stability coefficient calculation, the stability coefficient of plane type was the lowest, and the other two modes could both meet the security requirements.However, the stability coefficient of circular arc failure mode was a little lower.Therefore,taking targeted reinforcement measures against the two failure modes should be recommended.
