摘　　要：嘉兴电厂二期取水工程是国内首次采用沉管法在海底建设的取水隧道,工程具有海象与地质条件复杂、海上浮运沉放次数多以及对沉放精度要求高等特点。扼要介绍的管段浮运、沉放施工等技术,可供其它类似工程借鉴与参考。The water intake project of Jiaxing Power Plant (2nd phase) is the first immersed tunnel under sea in China. The project features with the complex marine and geology condition, float and immersion several times, high degree of accuracy for immersion. Tunnel element's float and immersion technologies are introduced for other similar project's reference.
