某水库库岸滑坡机理和治理方案分析

Analysis on Mechanism and Treatment Scheme of a Reservoir Bank Landslide

文中以某水库库岸滑坡治理工程为载体,针对该滑坡变形特征进行分析,研究了该滑坡形成机理及失稳破坏模式。通过稳定性反算,结合土体室内试验参数确定了滑坡体滑面强度参数,对该滑坡稳定性进行了评价分析。结果表明,该滑坡体在各设计工况下安全系数不满足规范要求,需对其进行加固治理。经多方案比较,最终采用抗滑桩和截排水措施进行治理,效果良好。

Taking the landslide treatment project of a reservoir bank as the carrier, this paper analyzes the deformation characteristics of the landslide, and studies the formation mechanism and instability failure mode of the landslide. Through the stability back calculation, combined with the soil indoor test parameters, the strength parameters of the sliding surface of the landslide are determined, and the stability of the landslide is evaluated and analyzed. The results show that the safety factor of the landslide mass under various design conditions does not meet the requirements of the specification, and it needs to be reinforced and treated;After comparison of many schemes, anti slide piles and interception and drainage measures are finally adopted for treatment;The monitoring results show that the treatment effect is good.
