摘要
目的研究建筑物基础全部或部分在岩质坡体内,边坡稳定安全系数的简化计算公式.方法按极限平衡理论中的平面滑动破坏和楔体破坏两种破坏模式进行稳定性分析.结果根据建筑物基础全部或部分在坡体内以及不同的破坏模式选择合适的安全系数计算公式,对建筑物基础部分在坡体内时,有些只须通过提高边坡稳定性的构造措施就可确保边坡的安全.结论边坡稳定安全系数计算公式为建筑荷载作用下的边坡稳定设计提供了有益的参考.
Objective The research about the rock slope stability under the load of building is carried out here. Formulas are presented to calculate the safety coefficient by simplifying methods under the load of building. Methods Based on the two failure mode of plane and wedge sliding destruction of the limit equilibrium theory, rock slope stability is analysed. Results According to the model of embedded part or embedded full of the foundation in the rock slope, different failure mode and safety coefficient calculating formulas can be used. While foundation is embedded in slope by part, some constructional measure can be used to raise slope stability. Conclusion Safety coefficient calculate formulas to slope are useful for evaluating the slope stability under the load of building.
