桥梁施工过程的仿真分析研究

桥梁的精确分析必须与其施工方法,施工过程紧密联系。在施工过程中,结构的自重和施工荷载都是在各施工阶段逐级施加的,而且每一阶段伴随着徐变、收缩,预应力的张拉,边界约束的增减和体系转换等因素。所以导致通用的结构分析程序应用于桥梁结构分析存在一定的局限性。对此,该文阐述了有关桥梁施工过程的仿真分析研究。基于Visual Basic6.0开发了桥梁分析程序系统,以解决对桥梁进行精确分析的问题。实践证明该程序使用方便,结果可靠。

Study on Simulation Analysis of Bridge Construction Process

The accurate analysis of bridge must be closely related to its construction method and construction process.The deadweight and construction load of the structure are all applied in each construction stage step by step in the construction process,and with the factors of creep,constriction,prestressing tension,increment and decrement of boundary constraint,and system conversion,the application of the general structural analysis program in the bridge structural analysis is resulted in a certain limitation every stage.Therefore,the article sets forth the simulation analysis study of the bridge construction process.The bridge analysis program system is developed on Visual Basic 6.0 to solve the problem in the accurate analysis of bridge.The practice proves that this program is convenient for application and its result is reliable.
