通过介绍沿江开发高等级公路(南京江北段)工程滁河大桥主桥的系杆拱的安装施工过程的详细介绍,为今后的系杆拱桥的安装施工积累了一点经验。滁河大桥主桥设计形式为下承式系杆拱,横跨滁河,施工过程河道不能中断,主桥两端各有近80m的河滩,无法采用支架现浇法和缆索法,故而采取少支架法。结合滁河大桥主桥的实际情况,来浅谈一下系杆拱桥少支架法安装施工的质量控制。
Through introducing the construction process of the tied arch of the main bridge of the Chuhe River Bridge along the Yangtze River to develop the high-grade highway (Nanjing Jiangbei section), we have accumulated a little experience for the installation and construction of the tied arch bridge in the future. Chuhe Bridge main form of design for the under-tied tied arch, across the Chu River, the construction process of the river can not be interrupted, the main bridge at both ends of each have nearly 80m of flood beach, can not use the stent pouring method and cable method, so take less Stent method. Combined with the actual situation of the main bridge of Chuhe Bridge, to talk about the quality control of the installation and construction of the tie-bar arch bridge less bracket method.
