小半径曲线桥梁预制安装设计及有限元分析

Prefabricated Installation Design and Finite Element Analysis of Small Radius Curved Bridge

针对小半径平曲线预制安装桥梁梁板架设顺序施工方案,拟通过BIM结合有限元分析软件,对小半径曲线梁桥梁板架设进行方案比选,根据实际情况制定合理的梁板架设方案,模拟桥梁吊装施工过程,通过方案比选,确定梁板最优吊装顺序,保证架梁过程的安全性、高效性,制定科学合理的控制措施,确保曲线桥的梁板架设位置准确。

In view of the construction scheme for the erection sequence of the beam of the small radius horizontal curve prefabrication installation bridge, it is proposed to compare and select the schemes for the erection of the beam of the small radius curved bridge through BIM combined with the finite element analysis software. The reasonable beam erection scheme is made according to the actual situation, so as to simulate the hoisting construction process of the bridge. The optimal hoisting sequence of the beam is determined through the scheme comparison and selection, so as to ensure the safety and efficiency of the beam erection process, formulate the scientific and reasonable control measures and ensure the accurate beam erection position of the curved bridge.
