钢箱梁开启桥施工过程有限元分析

Finite Element Analysis of Construction Process of Movable Bridge with Steel Box Girder

以海河开启桥为工程背景,建立施工全过程的空间数值分析模型,探讨了钢箱梁开启桥的力学性能特点,分析了其应力水平及其分布特点,为海河钢箱梁开启桥安装施工提供了技术参考。该桥的分析方法可供同类桥梁施工参考。

The movable bridge at Haihe river is taken as an example in this paper. A 3-D numerical analysis model, taking into account the complete process of construction, is established to study the mechanical charac- teristics of the movable bridge with steel box girders, he stress level and distribution characteristic of the movable bridge is analyzed, which provides technology reference for the construction of Haihe river movable bridge with steel box girders. The finite element analysis method of this bridge is suitable for similar bridge construction.
