引汉济渭工程黄池沟0号复活滑坡体治理技术研究

Research on the treatment technology of the No.0 reactivated landslide body at Huangchigou in the Hanjiang River to Weihe River Water Diversion Project

滑坡体受外界因素诱使复活,对工程造成安全隐患。本文以引汉济渭工程黄池沟0号复活滑坡体为研究对象,使用Slide边坡稳定分析软件建立模型,采用摩根斯顿-普赖斯法和简化Bishop法对0号滑坡体整体及次滑坡体进行天然、暴雨和地震三种工况下的稳定性分析,综合考虑安全、经济、施工因素,采用了局部开挖+路边全埋式抗滑桩+锚索加固施工方案,经模型稳定性分析,该方案能够满足1级边坡稳定性规范要求,有效地预防滑坡体再次复活,保障了工程项目的实施。

Landslide bodies can be reactivated by external factors,posing safety hazards to engineering projects.This paper takes the No.0 reactivated landslide body at Huangchigou of the Hanjiang-to-Weihe River Water Diversion Project as the research subject.Using the Slide slope stability analysis software,models are constructed,and the stability of the No.0 landslide body and its secondary landslide bodies are analyzed under natural conditions,torrential rain,and earthquakes using the Morgenstern-Price method and the Simplified Bishop method.Considering safety,economic,and construction factors,a construction scheme involving partial excavation,roadside fully buried anti-slide piles,and anchor reinforcement is adopted.The model stability analysis confirms that this scheme meets the requirements of Level 1 slope stability standards,effectively preventing the reactivation of the landslide body and ensuring the implementation of the project.
