为了有效减低港口回淤量,经多种防波堤结构类型的对比设计计算及技术经济分析,天津港北防波堤延伸二期工程采用钢筋混凝土箱筒型基础。文章对该防波堤的施工方法进行了介绍,该工程构件体积大、工艺复杂、海上施工现场条件差、工期紧,与斜坡堤、半圆型防波堤比较,在质量、造价、工期等方面具有优势。

To effectively minimize the siltation in Tianjin Port and after the comparison,design calculations and technical and economic analysis of various types of breakwater structures,a reinforced concrete cylindrical caisson structure was adopted for the second phase of the extension of the northern breakwater in Tianjin Port.The paper gives a description of the construction procedures of the breakwater.The structural members were massive in size and complex in technological process while the offshore conditions on site were severe and the construction duration was tight.Comparing with the rubble mound breakwaters and semi-circular caisson breakwaters,a breakwater of reinforced concrete cylindrical caisson structure is preponderant in quality,cost and construction duration.
