桩基地连墙码头结构新形式应用与研究

埃及塞德港集装箱码头二期工程成功应用桩基地连墙码头结构，项目设计过程采用三维有限元方法、考虑桩土相互作用进行结构计算，采用修正的竖向弹性地基梁法进行结构内力计算，整体稳定性计算考虑截桩力。项目在结构形式和设计计算方法方面均具有创新性。桩基地连墙组合码头结构，是介于桩基和地连墙结构间的新型结构，较适用于软弱土层较厚、具有陆上施工条件的大中型码头结构。

On wharf structure with pile and diaphragm wall

In Egypt Port Said Container Terminal Phase II, the wharf structure with pile and diaphragm wall was successfully applied, and the three-dimensional finite element method was adopted for the structure calculation under the consideration of the pile-soil interaction. The structural internal force was by the modified vertical elastic foundation beam method, and the overall stability calculation took the cut-off pile power into consideration. The project design was innovative in both the structural type and the .calculation method. The wharf structure with pile and diaphragm wall is between the pile and diaphragm wall, and is more suitable for medium-large terminal structures with thick soft soil and favorable land construction conditions.
