| 摘 要： | 中心渔港东隔埝工程远期规划为游艇码头,故需采用直立结构。通过反复比选,隔埝采用预应力板桩结构,锚碇结构采用锚碇叉桩。由于预应力板桩结构较为敏感,文章详细介绍了在软土地基不利情况下的结构优化设计。通过本项目,拓展了板桩结构使用前景,获得了显著的经济收益。

| Abstract: | A vertical structure was adopted for the east cofferdam for Tianjin central fishing port as the east cofferdam has been planned for a yacht marina for the long term development.Prestressed sheet-piles were selected for the cofferdam construction after repeated comparison and anchoring braced pile was used in anchoring structure.As a prestressed sheet-pile structure is rather sensitive,this paper has in detail illustrated structural optimization design under the adverse conditions of soft earth foundation.The prospect of sheet-pile structure application has been expanded and striking economic gain has been achieved by the execution of this project. |
