广东省大埔县赤羌坪滑坡稳定性评价及防治对策

Stability analysis and control measures of Chiqiangping Landslide in Dapu county of Guangdong Province

由于赤羌坪地质环境条件及不利气象因素影响,致使古滑坡复活,直接威胁当地群众生命财产及道路交通安全。本文在滑坡地质灾害勘查的基础上,分析了影响滑坡稳定性的因素,采用剩余推力传递法进行滑坡稳定性定量评价,得出:天然状态下,滑坡处于不稳定状态,在持续降雨及强降雨作用下,稳定程度进一步降低,随时有大规模滑动破坏的危险。为此,提出了"排水+锚索抗滑桩支挡"工程治理方案对滑坡进行工程治理。

Because of the effect of Chiqiangping geological environment conditions and unfavorable weather factors,the ancient landslide becomes active again and this is a direct threat to life and property of the local people and road safety.This paper analyses the factors affecting the slope stability and carries on the quantitative evaluation over the stability by residual thrust transfer method,which is based on the prospecting of landslides hazard,and it draws a conclusion that： under natural conditions,landslides are in the unstable state;in the continuous rain and strong rainfall,the stability gets further reduced and there’s always the danger of large-scale sliding failure.Therefore,this paper presents a ＂Drainage ＋ Anchor Rope Anti-slide Pile＂ engineering management program to deal with the landslide management project.
