南欧江六级水电站复合土工膜面板监测资料分析

Analysis on Monitoring Data of Composite Geo-membrane Panel of Nam Ou 6 Hydropower Station

老挝南欧江六级水电站挡水建筑物为目前世界上最高的土工膜面板堆石坝,也是软岩填筑比例最大的面板堆石坝[1]。为了保证土工膜面板堆石坝的长期稳定运行,对堆石坝面板表面的土工膜进行了土工膜变形和土工膜内部浮托力等专项监测。通过对监测资料的整理和分析[2],为该坝的安全运行提供有力保障,同时也为土工膜面板堆石坝的设计、施工提供科学依据。

The water retaining structure of Nam Ou 6 Hydropower Station is the highest geo-membrane faced rockfill dam in the world at present, and it is also the rockfill dam with the largest proportion of soft rock filling [1]. In order to ensure the long-term stable operation of the geo-membrane faced rockfill dam, the geo-membrane deformation and the uplift load inside the geo-membrane were monitored. By sorting and analyzing of monitoring data [2], it can provide a strong guarantee for the safe operation of the dam, and also provide a scientific basis for the design and construction of geo-membrane faced rockfill dam.
