三峡库区重庆市开县渠口镇滑坡的稳定性分析及治理措施

摘要

结合三峡库区重庆市开县渠口镇滑坡的工程实例,分析了滑坡的基本特征、影响因素,计算并分析了滑坡的稳定性,提出了该滑坡的治理措施。结果表明,滑坡在三峡水库蓄水前整体是稳定的;在三峡水库蓄水后,滑体处于基本稳定状态;在考虑库水位和暴雨时,处于基本或不稳定状态;该滑坡按两期进行分期治理,一期工程为滑坡监测、排水、封闭裂隙与灌浆护岸相结合,二期工程为抗滑桩、削坡减载与回填反压相结合。%Combined with the engineering example of the Jukou Town landslide in Kaixian County, Chongqing, Three Gorges Reservoir Area, the paper construes the basic characteristics of and the factors affecting the landslide, calculates and analyzes its stability and proposes the treatment measures. The results show that the landslide is stable as a whole before water storage in Three Gorges Reservoir; after the storage, it stays stable basically; and taking water level in the Reservoir and torrential rain into consideration, it will be in the status of basic stability or instability. Thus the landslide is treated in two phases with the first phase combining supervision, drainage, fracture closing and bank protection by grouting and the second phase combining anti-sliding piles, cutting work to reduce load and backfill compaction.
