摘要
乌东德水电站泄洪洞工作闸室具有体型复杂、挖空率高、埋深较大等特点,立足时空交叉施工组织理念,通过采取一系列施工关键技术,实现了大断面尺寸效应和洞室群效应显著条件下的安全施工,同时合理的规划布置确保了施工过程连续高效,成功实现了安全快速施工,获得了良好的工程效益。
he lock chamber of Wudongde Hydropower Station possess the characteristics of complex shape, high rate of excavation and large embedment depth. Based on the construction organization concept of multiple crossover Space-time intersection, safe construction is realized in the condition of the palpable size-effect of largespan and the excavation effect of tunnel group by taking a series of key construction technologies. Meanwhile, high efficiency and continuous construction is guaranteed with reasonable planning-layout. This study provides reference for similar projects.
