STUDY OF CONSOCIATION BEARING OF ARCH RING AND ARCH CENTERING IN SUB-RING CONSTRUCTION OF CONCRETE BOX ARCH BRIDGES

摘要：

In this paper,an advanced finite element analysis software MSC.Marc written by the United States,is used to analyse the force of Central Box - Arch centering in the process of sub-ring construction and calculate accurately the combined effect of the arch ring,basing on a demonstration bridge in Sichuan. Finally the concrete weight ratio the arch centering could bear can be concluded. The result of the theoretical analysis is validated by the detailed monitoring in the process of sub-ring construction. In Februrary 2007,the bridge successfully completed and opened to the traffic. In order to make the research result easy to promote ,in this paper,five simulant arch bridge of different span are chosed for the emulational anaylsis,which explores the linear equation of arch ring concrete weight ratio,and this can be as a reference for similar engineering projects.
