摘要
针对南鹤公路东乡村滑坡治理工程,运用北京理正软件对治理前后的天然、暴雨两种工况进行稳定性分析。结果表明:天然工况下滑坡处于基本稳定状态;暴雨工况下滑坡处于不稳定状态。为此,对滑坡体采用锚索框架梁治理,对不稳定斜坡体采用锚杆框架梁防护,在边坡裂缝外侧设置预制混凝土U型截水沟,治理后滑坡体处于稳定状态,治理效果良好。
Taking the Dongxiang Village landslide control project of Nanhe Highway as an example, the stability analysis under natural and rainstorm conditions before and after the treatment is carried out by using Beijing Lizheng software. The results show that the landslide is basically stable under the natural working condition. Under the rainstorm condition, the landslide is in an unstable state. Therefore, anchor cable frame beam is adopted to treat the landslide. The unstable slope body is protected by anchor rod frame beam, precast concrete U-shaped intercepting drain is set outside the slope crack, climbing plants are planted inside the frame beam.The slope is in a stable state after treatment and the treatment effect is good.
