摘要
双江口水电站大坝为砾石土心墙堆石坝,最大坝高314m,是世界最高的心墙堆石坝工程。大坝上、下游围堰防渗墙的建造成败直接影响到大坝基础的开挖。主要介绍上、下游围堰防渗墙导墙下部覆盖层加固、巨漂孤石、倒悬体、超高陡坡地层的施工技术。
The dam of Shuangjiangkou hydro-power station is a rock fill clam with gravel-soil eore, and the dam is 314 meters high, which is the highest building in the world on this type. The construction quality of the cut-off wall for the up and downstream of the dam can direetly affect the excavation of the dam foundation. This paper mainly introduces the construction technologies of the covering layer reinforcement for the guide wall of the cut-off wall from the upstream and downstream of the cofferdam, the giant boulder, the overhanging structure and the ultra high abrupt slope stratum.
