摘　　要：随着社会的进步,国内桥梁结构多样化、施工技术日趋成熟,各种新兴结构应运而生,对桥梁结构设计的合理性、使用的安全性、长久化、结构的轻量化提出了更高的要求,钢-混凝土叠合梁桥便是兼具以上诸多特点的新型结构桥梁,但整体桥面系受力较为复杂,每进行一步施工都有可能影响桥梁整体质量和受力性能,为此需要在桥梁施工全过程中使用BIM软件、利用有限元程序ANSYS对桥梁主体结构建立完整、统一的桥梁结构仿真分析模型,全程模拟计算,分析各施工阶段的的受力特点,在施工过程中检测每道工序施工后,桥梁的应力与挠度,为下一步施工提供科学依据和理论基础。With the advancement of society, the domestic bridge structures are diverse, the construction technologies are becoming mature, and a variety of emerging structure come into being. The higher requirements for the rational design of the bridge structure, safety of use, duration, and lightweight structure are put forward. The steel – concrete composite beam bridge is a new structural bridge with the above advantages. But its overall deck system stress is more complex. Each step of construction is likely to affect the overall quality and stress performance of bridge. Therefore, it is required to use BIM software in the whole process of bridge construction, and to use the finite element program ANSYS to establish a complete and unified bridge structure simulation analysis model for the main structure of bridge so as to carry out the whole process simulation calculation and the analysis the stress characteristics of each construction stage, and the bridge stress and deflection after every step of construction is tested in the construction process, which can provide the scientific basis and theoretical basis for the next step of construction.
