四川省某水电站左坝肩堆积体稳定性评价

Stability Evaluation of Debris Located on the Left Dam-abutment of Some Hydropower Station in Sichuan Province

研究的堆积体位于四川省西溪河流域某水电站左坝肩上部,其失稳不但影响大坝施工,而且将对电站枢纽建筑物安全构成直接威胁。现今在其地表出现多条裂缝,因此对其稳定性进行分析研究迫在眉睫。在地质测绘、现场勘察及岩土试验等资料的基础上,对堆积体的稳定性进行了评价。

The debris located in the upper of the left dam-abutment,Xixi River in Sichuan province.The stability of the debris affects not only the dam construction,but also the security of the key building directly.Its stability analysis is imminent owing to many surface cracks.The stability of the debris was evaluated based on geological mapping,geotechnical site investigation and the crag earth experiment and so on.
