| 摘 要： | 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。

| Abstract: | Stability of a high rock slope is analyzed.The classic Sarma principle is introduced and modified by some external loads such as anchor-hold in view of engineering conditions.Based on the method,stability of 4 representative sections of a certain high slope is analyzed in two different conditions,which is consistent with the qualitative result by criterion.Furthermore,the high slope is reinforced and the reinforced project is analyzed.It is shown that the modified method is simple and effective for the stab... |
