桩基-重力式复合结构码头的有限元分析

通过大型有限元计算软件ANSYS,对荷载作用下的某桩基-重力式复合结构码头内力进行三维空间有限元分析。选择两种不同地基模型来模拟沉箱与地基的相互作用,结果表明,文克勒地基模型与半无限空间地基模型,除沉箱地板内力有一定差别外,码头结构其它部位内力基本相同,且两种模型中桩基与底部沉箱的连接处的节点应力较大,设计时有必要对此处进行加强。

Finite element analysis of pile-gravity type complex wharf

Finite element procedure ANSYS was used to analysis internal force of a pile-gravity type complex wharf under different load effect. Choosing two different ground-based models to simulate the interaction between caisson and foundation, the results show that Terminal structure internal forces is basically the same except some different in caisson bottom under Winkler foundation model and the model half-space foundation.The stress of the node which is in the location of piles and caissons connected is very large, so it is necessary to strengthen in this place.
