摘要

以某8度区城市快速路高架桥为依托,选取一标准联装配式简支变连续小箱梁结构为研究对象,分别采用常规结构体系(板式橡胶支座)和减隔震结构体系(铅芯隔震橡胶支座)进行结构抗震设计,比较不同支座设计体系下结构的具体抗震性能,结果表明减隔震体系具有更优的抗震性能。
The old bridge utilization is the difficulty of urban road construction.Combined with the practical project of old bridge utilization of Xianzhuang Interchange,the article analyzes and studies the selection of old bridge utilization mode.The inspection and check understand the status of the existing old bridge of Xianzhuang Interchange.Based on the function demand and construction condition of Guangming Expressway and Xianzhuang Interchange,the old bridge utilization schemes are compared and selected.The spatial finite element model is established to simulate the mechanics action connecting the new bridge with the old bridge,and it is taken as the basis for the widening and reinforcing work of old bridges.The analysis on the old bridge utilization scheme of Xianzhuang Interchange will be referred for the utilization of the old bridges in the other projects.
