某桁架拱桥加固后静力试验分析

Static Experimental Study of the Reinforced Truss Arched Bridge

本文以加固后的克山老桥为研究对象,利用MIDAS/CIVIL桥梁专用分析软件计算结果与静载试验结果进行对比分析,表明该桥在活载作用下满足加固维修设计要求,为该桥加固工程验收提供依据,并为同类工程提供了参考。

This article take the reinforced Keshan old bridge as a research object. Based on MIDAS/CIVIL program special calculation results and static experiment results, comparison and analysis is contained. This shows that the bridge meets the design requirements reinforced maintenance under the vehicles load. So it is provided a basis for acceptance for the bridge and a value reference for this kind of bridge reinforcement design.
