长江三峡库区地质环境条件极为复杂,由于三峡工程的兴建,库水位的上升将诱发大量滑坡.本文选取湖北省巴东县老城区三峡教育服务公司滑坡为工程背景,在对地质环境条件和变形破坏特征进行调查研究的基础上,对产生滑坡的原因进行了深入分析,并概括出了滑动模式.采用不平衡推力法,对各种工况下的滑体稳定性进行了计算,结果表明:该滑坡在现今天然状况是稳定的,但在降雨或水库蓄水时,该滑坡整体处于潜在不稳定状态,必须进行地表排水、抗滑桩和挡土墙等综合整治措施.
Due to the construction of Three Gorges Project, a large number of landslides will be induced due to the rise of reservoir water level.This paper selects the landslide of Three Gorges Education Service Company in Laocheng District, Badong County, Hubei Province as the engineering background, and analyzes the geological environment conditions and deformation Based on the investigation and research on the characteristics of the landslides, the causes of the landslides are analyzed in depth and the sliding modes are summarized. The stability of the landslide under various conditions is calculated by the unbalanced thrust method. The results show that: The landslide is stable under natural conditions. However, when the rainfall or reservoirs are impacted, the landslide is in an unstable state as a whole. Therefore, comprehensive treatment measures such as surface drainage, anti-slide piles and retaining walls are necessary.
