三峡工程规模巨大，技术复杂。文章介绍了三峡工程建设在大江截流和混凝土防渗墙施工技术、大坝混凝土快速施工新技术、船闸高边坡施工技术、电站大型钢衬钢筋混凝土压力管道和蜗壳保温保压技术、沥青混凝土心墙、船闸金属结构、水轮发电机组等重大技术问题上的突破。

The huge Three Gorges Project is technically complex. Quite a lot of technical breakthroughs have been made on the issues such as river closure of the Grand Channel and concrete construction of the cutoff wall, prompt concrete construction of dam, high slope construction of permanent shiplock, large-scale steel-lined reinforced concrete penstocks of power station and temperature and pressure maintaining of the spiral case, asphalt concrete core wall, metal works of the shiplock, turbine generating units, and so on.
