摘要
毛家河水电站堆积体主要由松散工程地质岩组和完整性差的软质工程地质岩组组成。堆积体边坡上各种永久和临时建筑设施的重建和运行,破坏了堆积体边坡原始地形地貌,加之强降雨的影响,加剧了坡体的变形破坏。采用理正岩土计算软件对毛家河水电站堆积体滑坡进行稳定性计算,结果显示堆积体在正常工况下处于稳定状态,在暴雨或连续降雨状态下处于不稳定状态,遭遇强降雨还会继续滑动。提出对堆积体采用削坡减荷、排水、抗滑桩等综合治理方案。
The Maojiahe Hydro-power Station deposit is mainly composed of loose engineering geological petrofabric and soft engineering geological petrofabric of poor integrity. The rebuilding and operation of permanent and temporary facilities on the deposit slope destroyed its original topography. The heavy rainfall further aggregates the slope deformation and destruction. Based on the software of Lizheng Geological Structure Designing, the article analyzes its slide stability in the Maojiahe Hydro-power Station. It is found that the deposit under normal condition is stable. Under a heavy rain or continuous rainfall condition, it is unstable. Under a torrential rain, it will continue to slide. It is proposed to take comprehensive control measures, such as slope-cutting, load reducing, drainage, anti-slide piles to harness landslide.
