摘要:
在施工过程中大跨度系杆拱桥一般采用逐步拼装法进行安装,导致实际施工中材料力学参数与设计有一定的差异。该项目为大跨度下承式钢箱系杆拱桥,为保证桥梁在施工过程中所经历的体系转变趋于稳定,需采用一定的技术手段对其全程进行监控。采用Midas/Civil有限元分析软件建立计算模型,通过监控计算和施工监测,对施工过程中的结构内力和位移进行有效地分析、计算和预测,控制大跨度拱桥的最终线形在设计允许的误差范围内,从而保证桥梁在全生命周期的安全性和耐久性。研究表明,软件计算值与实际监测成果较为符合,为现场施工提供了一定的理论支持。
Abstract:
In the construction process, the large span tied -arch bridge generally adopts a step-by-step assembly method, which often results in certain differences between mechanical parameters and displacement of the material in actual process. This project is about monitoring of large-span under-supported steel box tied-arch bridge. In order to ensure that transformations of the system in the bridge construction can sustain stable phenomenon, it is necessary to use a certain technique to monitor the whole process of bridge construction. The calculation model about the scheme is established by software of finite element analysis called Midas/Civil. Through construction monitoring, internal force and displacement of the structure during construction are effectively analyzed, calculated and predicted to ensure final linearity shape of large-span steel box bridge within the scope that design can be permitted, as well as the safety and durability of the bridge throughout its life cycle. The research indicates that the calculation is conformed with the monitoring data. In the future it can supply a certain support for construction site.
