| 摘 要： | 由于莲河村山体特殊的地质背景及居民人工开挖坡角,在莲河村"村村通"公路东北形成两个规模不等的小型滑坡,直接威胁坡底多户居民的生命财产安全。通过地质灾害勘查,分析了影响滑坡稳定性的因素,建立了滑坡的概化模型,采用传递系数法进行了稳定性的定量评价,天然状态下,两个滑坡均处于欠稳定状态,但在暴雨久雨的条件下,滑体处于不稳定状态。为此,提出了对Ⅰ号滑坡采用坡脚抗滑桩阻滑,后缘削坡减载和前缘回填反压、Ⅱ号滑坡采用坡脚修建挡土墙,滑坡外围修建截、排水沟,滑坡前缘回填压脚的科学安全又经济的防治措施。

| Abstract: | Because of the special geological settings and the slope foot digging,two landslides in different scales were becoming in Lianhecun,which threatened the safety of the residents near the slope.Based on the geological hazard investigation and analysis of the landslide stability affecting factors,a general model of the landslides was established.Safety of the two bodies was quantitatively assessed using the method of delivering coefficient.The result showed that the two landslides were less-stable under normal... |
