南宁仙葫大桥桥墩钢围堰分析和优化

Analysis and Optimization on Main Pier Cofferdam of Xianhu Bridge in Nanning

利用大型通用有限元程序Ansys对南宁仙葫大桥桥墩钢围堰进行强度和变形分析,在此基础上对结构提出了优化方案,并对原结构和优化结构的强度和变形进行比较。结果表明,新方案既能够满足工程要求,又具有节约材料、经济性好、便于后续施工作业等优点。

The optimized project for structure was obtained based on analysis on main pier cofferdam of Xianhu bridge in Nanning using large common finite program ansys, the strength and distortion of old structure and optimized structure was compared at the same time. As the result shown, the new project can not only satisfy the engineering requirement but also have many advantages, such as saving materials, economical, convenient for later constructure.
