摘　　要：某桥主桥上部结构为计算跨径84m的下承式钢管混凝土拱桥,介绍对该桥进行的施工监控前期的优化计算,以及施工监控过程中的优化计算。计算结果作为指导施工的依据。The superstructure of the main bridge of a bridge is a through bowstring arch bridge of concrete-filled steel tubes with calculated span length 84 m. This paper presents the optimization calculation of monitoring and control at both the early stage and in course of the construction of the bridge. The results of the calculation have already served as the guidance to the construction of the bridge.
