波浪力作用下考虑时空效应坞口围堰钢板桩优化设计研究

Optimization design and research of steel sheet pile for dock port cofferdam under the action of wave force in consideration of time-space effect

结合某船坞坞口围堰基坑工程实例,考虑基坑支护施工的时空效应,针对波浪力作用及多施工工况下钢板桩结构进行优化设计计算,分析验算钢板桩的承载力和稳定性,以满足规范要求。

In combination with an engineering example of a dock port cofferdam foundation pit, and in consideration of the time space effect of the foundation pit sup- port construction, optimization design and calculation were carried out for the steel sheet pile structure under wave force action and multi-construction working condi- tions, the bearing capacity and stability of steel sheet pile were analyzed in order to meet the standard requirements.
