对某岩质高边坡进行了稳定分析,引入了经典的Sarma方法,考虑锚杆锚固力等外部荷载,扩展了Sarma法,并根据工程具体情况采用了不同的荷载组合项,对某高边坡四个代表区段在两种不同工况下进行了稳定分析,得出该边坡各区段的稳定系数,其稳定性判断与规范定性判断结论是一致的。在此基础上,对高边坡进行了加固处理,并运用该方法对加固方案作了稳定分析,证明该方法简单有效,适用于岩质边坡稳定分析。
A stable rock slope was analyzed. The classical Sarma method was introduced, and the Sarma method was extended by considering the external load such as the anchorage force of the anchor. Different load combination items were adopted according to the engineering conditions, The four representative sections of the slope are analyzed in two different conditions. The stability coefficients of each section of the slope are obtained. The stability of the four sections is consistent with that of the standard qualitative judgment. On this basis, the reinforcement of the high slope is carried out. The stability analysis of the reinforcement scheme is made with this method, which proves that the method is simple and effective and can be applied to the stability analysis of rock slope.
