摘　　要：介绍了张河湾抽水蓄能电站4号路支线连续刚构桥的监控内容、监测方法以及对结构的理论分析过程,并对该桥在施工过程的各个阶段进行了结构分析计算,为本桥的监控提供了理论依据。监控和监测结果表明,主桥合龙顺利,结构应力状态符合设计要求。The supervision and control content of and methods for the continuous steel rigid bridge of the Branch Line of the Fourth Road to the Zhanghewan Hydropower Station are introduced in the paper, with the theoretical analysis process of its structure provided. The structural analysis calculations performed at various stages of its construction are also provided, which provide a theoretical basis for the supervision and control of the bridge. The results of the supervision and control and the monitoring prove that the closure of the main bridge is smooth and the structural stress state is up to the design requirement.
