天津港二突堤转角区域码头结构与土体三维有限元分析

3D finite elements method analysis on wharf structure and soil in the corner of No.2 croy of Tianjin Port

近年码头调查发现,天津港多个突堤转角区域的码头结构变形和横向错位情况十分严重,这与以前发现和认识的规律有所不同。文中从这些问题入手,以天津港二突堤为对象,系统地研究了该突堤转角区域码头结构和岸坡相互作用机理和变形特点,并指出突堤转角区域的码头结构受力比较复杂,其变形具有空间变化特点,传统的二维分析和设计方法是不够全面的。

It is showed by survey data that more serious deformation of the wharf structure occurred on the joint zone of the shore and croy. It has some differences from what we knew before. In order to solve these problems, this paper made a research on the piled wharf and slope interaction in the zone. The paper also points out the interaction between the soil and structure is complex. Because the deformation of the structure has the place characteristic, the traditional 2D analysis and design method is insufficient.
