某跨海大桥施工承台桩靴的结构分析与优化

Structural Analysis and Optimization for a Pile-boots Stucture of Constructing Platform in a Crossing sea Bridge

采用大型有限元分析软件 AN SYS5.7对工程实际问题——某跨海大桥施工承台桩靴结构 ,进行了有限元建模和计算分析 ,指出原设计方案会在顶板和底板产生比较大的应力和位移 ,不能满足工程实际的需要 .利用 ANSYS自带的优化求解器 Design Opt对结构进行了优化 ,得到优化后的结构尺寸 .并为同类结构分析提供了参考 .

Based on the FEA software ANSYS5.7, a Pile boots structure of the constructing platform in a crossing sea bridge is modeling and analysing, and great stress and displacement are found in the roof plane and base plane with the original scheme. So it’s infeasible in the engineering. Then the structure is optimized with the Design Opt of ANSYS, and more rational structure is gotten. It may also offer reference to the same kind of structure.
