摘要：

文章总结了在长江口深水航道治理二期工程中,于无掩护外海,风浪大、涨落潮流速大、水域泥砂含量高的恶劣海况下,出运、安装544个半圆型沉箱的施工工艺。其中包括沉箱的水平运移、出运下水、沉箱的定位和安装。

The paper summarizes the technology for launching,transportation and installation of 544 semi-circular caissons in unsheltered seas with high winds and waves,high current velocity when the tides ebb and flow,and high sediment content in the water area during the execution of the works to train the deepwater waterways in the Changjiang Estuary.The technology involved the horizontal shifting,launching and transportation as well as positioning and installation of the caissons.
