摘要
以佛山市番海大桥工程项目中60 m钢混组合箱梁桥为工程背景,运用MIDAS/Civil 2020有限元软件建立计算模型,对优化设计前后钢混组合箱梁进行结构受力、施工工期及投资成本进行分析。结果表明优化后的钢混组合梁桥能确保桥梁受力性能满足设计规范要求、同时缩短了施工建设工期、节约了成本,取得良好的社会和经济效益。
Based on 60m steel-concrete composite box girder bridge of Foshan Panhai Bridge Project,this paper uses the calculation model,which is built by MIDAS/Civil 2020 Finite Element Software,to analyze the structural force,construction sequence and investment cost of the steel-concrete composite box girder before and after the design optimization.The results show that the optimized steel-concrete composite girder bridge can ensure that the mechanical performance of the bridge meets the design specifications requirements,as well as shortens the construction period,saves the cost,and achieves good social and economic benefits.
