| 摘 要： | 杭嘉湖南排新兴桥工程是一座跨度为70 m的下承式系杆拱桥.针对该桥建设时遇到的临时借地费用高、安装风险大、影响社会道路通行等难题,提出了拱肋现浇的施工方法,并将其与预制吊装方案进行了技术性、经济性比较,认为系杆拱拱肋采用常规的混凝土现浇方案,在节约用地、保护环境、规避高空大吨位结构物吊装风险、节约施工成本等方面有较大优势.

| Abstract: | Nanxing Bridge is through bowstring arch bridge with the span of 70 meters in South Rowing Engineering of Hangzhou-Jiaxing-Huzhou District.The constructing approach of situ-casting arch rib is put forward in the paper in order to avoid the high cost,risky installation risky and traffic jam,which is also compared with precast hoisting in the perspectives of technology and economy.It proves that the concrete bowstring arch bridge by conventional techniques is superior in land and cost saving,environmental protection with less large-tonnage hoisting risk in high altitude. |
