钢－混凝土组合梁桥面结构施工阶段受力分析

摘要

In order to ensure construction quality and safety of reinforcement -concrete combined beams, this paper analyzes the force during construction of reinforcement -concrete combined beam bridge deck by means of numeric simulation method.In combination with construction of bridge No.1 in some highway passage project,the paper carries out 3D numerical simulation analysis for the whole process of construction of deck slabs and probes into forces on steel beams and concrete slabs of the actual bridge at various loading stages to provide a reference for construction of reinforcement -concrete combined bridge deck structures.%为确保钢－混凝土组合梁的施工质量和施工安全，采用数值模拟方法对钢－混凝土组合梁桥面结构施工阶段的受力进行分析。结合某公路通道工程1号桥施工，对桥面板施工全程进行三维数值仿真分析，探讨实际桥梁在各加载阶段的钢梁和混凝土板受力情况，为今后钢－混凝土组合梁桥面结构的施工提供参考。
