白格堰塞湖影响下叶巴滩水电站施工导流动态规划研究

Study on the Dynamic Planning of Construction Diversion of Yebatan Hydropower Station under the Influence of Baigeyansai Lake

在考虑白格堰塞湖影响下,对叶巴滩水电站施工导流规划进行动态调整研究。经过调整初期导流程序、实施分期围堰方案,保证了坝肩开挖工程尽早开工,降低了导流风险,挽回了工程损失;经综合经济技术比较,主体围堰推荐采用土石围堰结构型式,降低了工程投资,确保了主体工程施工顺利进行。

This paper makes a study on the dynamic planning of construction diversion of Yebatan Hydropower Station under the influence of Baigeyansai lake event.The adjusted initial diversion program and a multistage cofferdam scheme have ensured the dam excavation to be started as early as possible,reducing diversion risk and recovering project losses.The earth-rock main cofferdam is recommended after a a comprehensive economic and technical comparison,reducing investment and ensuring the smooth construction of main project.
