摘要/Abstract

摘要： 罗行滩滑坡是汉江孤山水电站库首的重要滑坡之一，系发育在崩坡积土层中的堆积层滑坡，体积约70×104 m3，属中型滑坡。据野外调查，初步分析滑坡目前整体处于基本稳定状态。分现状、暴雨和水库蓄水等3种工况对滑坡进行稳定性计算，结果表明：在现状条件下，滑坡基本稳定；在暴雨工况和蓄水工况条件下两侧滑体稳定性较差，中段滑体稳定性较好，但两侧滑体若失稳对中段滑体稳定不利。滑坡失稳对工程危害较大，建议滑坡治理结合大坝围堰填筑用料采取清除措施。

Abstract: Luohangtan landslide is one of the important landslides in Gushan hydropower station of Hanjiang, it is an accumulational landslide of collapsing soil, the volume is about 70 × 104 m3, it is a medium-sized landslide. According to a field survey, preliminary analysis shows landslides are stable for current state overall. For status quo，heavy rain and reservoir impoundment, the landslide stability is calculated, the results show that：in status quo conditions, the landslide is stable; under heavy rain and reservoir impoundment conditions, landslides on both sides are in poor stability, the landslide stability of middle part is better, however, the instability of landslides on both sides is bad for the stability of middle part. Landslide failure is more harmful to the project; using lardslide treatment combining with filling materials for cofferdam as removal measure is proposed

Key words: Luohangtan landslide, basic characteristics, formation mechanism, stability analysis, measures, Gushan hydropower station
