摘　　要：某电站输水管道桥为一简支钢桁梁。该桥建设年代较久,为了验证桥梁结构的安全性,需对全桥进行结构分析。将输水管道及桥梁在同一计算模型中建模,进行静力、稳定及抗震分析。经计算,发现桥梁结构存在部分杆件承载能力不足的问题。此外,尚有一些构造措施不满足规范要求。根据分析结论采取了有针对性的加固措施,加固后的桥梁各方面指标均满足规范要求,并成功经历了“9·5泸定地震”的考验。The water pipeline bridge of a power station is a simply supported steel truss girder.The bridge has been built for a long time.In order to verify the safety of the bridge structure,structural analysis of the whole bridge is needed.The water pipeline and bridge are modeled in the same calculation model for static,stability and seismic analysis.Through calculation,it is found that the bridge structure has the problem of insufficient bearing capacity of some members.In addition,there are still some structural measures that do not meet the specification requirements.According to the analysis conclusions,targeted reinforcement measures were adopted.All aspects of the bridge after reinforcement met the requirements of the specification,and successfully experienced the test of 9·5 Luding earthquake.
