| 摘 要： | 利用基于强度折减法的RFPA-Slope(Rock Failure Process Analysis)对支护下土质边坡的稳定性进行了模拟分析,直观地得到了坡体的滑移破坏面,并求得安全系数,与对应的无支护下边坡的滑移面模式、安全系数计算结果比较表明:支护措施发挥了很好的作用;对实例的分析说明RFPA-Slope能够较为准确地预测边坡潜在破坏面的形状与位置及相应的稳定安全系数,该方法对于复杂的边坡稳定性分析是实用的,特别是边坡破裂过程的模拟对于理解边坡的破坏形成机理具有重要的意义。

| Abstract: | The stability analysis of reinforced soil slope was conducted by using the RFPA-Slope incorporated with strength reduction theory.The failure surface of slope as well as the safety factor was achieved directly.Also the results for the case without reinforcements were numerically obtained and the comparison between the results show that the reinforcements in the slope work well.The case study indicates that RFPA-Slope can rather rationally predict both safety factor of slope and the corresponding shape and position of the potential slip surface.Accordingly,practical applicability of the proposed technique to complicated cases is verified,especially,the fracture process obtained with RFPA-Slope is significantly meaningful for the investigation of failure mechanism of slope. |
