大跨度系杆拱桥荷载试验方案与计算分析

本文对大跨系杆拱桥荷载试验方案及其计算进行了分析。首先,对桥梁荷载试验原理做了简要介绍,又以某大跨系杆拱桥为依托,对具体的静载试验和动载试验具体方案做了阐述;最后,采用Midas Civil有限元计算软件对静载试验及动载试验相关指标进行了初步分析。结合具体的试验结果,即可实现对桥梁承载力、裂缝、刚度及动力特性的评定。本文为同类桥梁的评定提供了依据,具有一定的工程实践意义。

Loading Test and Calculation Analysis for Tied Arch Bridge

This paper is about loading test and calculation analysis for tied arch bridge. Firstly, the principal of loading test is introduced briefly; And then, specific methods on static and dynamic tests are stated;Finally, preliminary analysis about static and dynamic test is conducted by using FEA software-Mi-das Civil. Combined specific test results, the information of bearing capacity, stiffness and cracks can be obtained. There-fore, the healthy evaluation of this kind of bridges is clear. This paper provides the basis for healthy evaluation of the same kind of bridges.
