    溪洛渡水库运行期干海子滑坡变形动态响应研究

    ON DYNAMIC RESPONSES OF GANHAIZI LANDSLIDE IN RESERVOIR ZONE DURING XILUODU PROJECT OPERATION

    • 摘要: 干海子滑坡是溪洛渡水库内距坝址最近的一个大型滑坡,伴随库水位升降发生了一定程度坡体变形与局部垮塌。由于干海子滑坡规模巨大,距离枢纽区不到14km,一旦发生大规模失稳,将导致灾难性后果。本文在系统分析水库运行过程中滑坡体宏观变形迹象、变形监测资料的基础上,详细研究了干海子滑坡体对库水位变化的动态响应规律,包括变形趋势、失稳方式、可能失稳范围及影响程度等,为水库运行管理、防灾减灾提供技术支撑。

       

      Abstract: Ganhaizi landslide is a large-scale landslide nearest to Xiluodu dam site in Reservoir zone. And with the water level fluctuation a certain deformation and partial collapse occurred in this landslide body. Because of its big volume and the distance to dam site less than 14km, disastrous consequences will be result in the event of large-scale instability. In this paper based on the systematic analyses about the macro deformation signs and the deformation monitoring data during the operation period, the dynamic response rules of Ganhaizi to reservoir water level fluctuation were studied in detail, including the slope deformation trend, failure mode, potential failure range and influence degree. Some technical supports for project operation management, disaster prevention and mitigation were provided.
