基于Midas的水中桥墩位上部结构支撑体系的设计方案与施工技术

Design Scheme and Construction Technology of Supporting System for Superstructure of Bridge Pier in Water Based on Midas

以花地河桥为例,介绍了水上施工时桥墩位置采用穿心钢棒建立的上部结构支撑体系的设计、施工及需注意的问题,通过采用有限元分析软件midas/Civil对支撑体系进行强度、挠度等相关验算,具有搭设便捷、提高工效的特点,同时为类似水上作业条件下的临时结构施工项目提供参考。

Taking Huadihe bridge as an example,this paper introduces the design,construction and problems to be paid attention to of the upper structure support system which is built by the steel bar passing through the center of the bridge pier during the water construction.The strength and deflection of the support system are checked by using the finite element analysis software midas/Civil.It has the characteristics of convenient erection and improving work efficiency,and provides reference for the construction project of temporary structure under similar water operation conditions.
