摘　　要：2012年6月,三峡库区大溪河曾家棚发生滑坡,该滑坡在库水位变动和暴雨共同作用下发生,其发生发展过程及形成模式在三峡库区具有典型代表性。通过对比曾家棚滑坡以往勘查测绘资料和本次滑动变形实测及调查结果,对该滑坡影响因素和成因机制进行了分析,并提出了其发展变化演化过程,预测了其发展变化趋势及危害性,可为库区相似岸坡稳定性分析及监测预警提供借鉴。Caused by the combined effect of the chang of reservoir water level and storm, Zengjiapeng landslide occurred in June, 2012, which had a typical representative for its evolutionary process and formation pattern in the Three Gorges Reservoir area. Contrasted the data by the previous drilling and mapping with the result of the de-formation measurement and investigation after slipping that time, influencing factor and formation mechanism for the slide were analyzed, and meanwhile its process of development and evolution was proposed, the deformation development trend and harmfulness were forecasted, all of which can supply a reference for the stability analysis, monitoring and early warning for the landslides similar to Zengjiapeng slope in the Three Gorges Reservoir area.
