摘要
三峡工程是当今世界上最大的水利枢纽。在三峡二期工程的6年建设中,不仅进一步推广了一期工程的科技成果,而且广泛引进、研究和应用了国内外先进技术和工艺:如防渗墙施工技术、大规模水平预裂爆破技术、混装炸药车技术、混凝土快速施工技术、塔带机浇筑技术、新型模板技术、钢筋机械连接技术、混凝土综合温控技术、沥青混凝土心墙施工技术、压力钢管自动焊接技术、多级船闸人字门联合调试技术、三期双戗堤截流技术等,成功地攻克了施工中的各项难题,取得了巨大的综合经济效益。
Three Gorges project is the largest hydraulic project in the world today. During the 6 years of construction of the second stage works of the Three Gorges project, the technieal aehievement gained in the first-stage works have been promoted and more new technologies and know-how from both China and abroad have been broadly introduced, studied and applied. Such technologies as construction of cut-off wall, large-scale horizontal pre-split hlasting, mixed-loaded dynamite trucks, rapid concreting, concreting by tower and bell-conveyor, newly developed tormwork, mechanical reinforcement connection, combined concrete temperature control method, construetinn of asphalt concrete core wall, automatic welding of penstock, joint adjustment of mile gates of the multi-stage ship-lock and the third stage river closure by double prop weir. Many technical problems have been successfully tackled during construction work and great overall economic benefits have been achieved.
