一、概述昌吉河56m系杆拱桥位于北疆铁路乌鲁木齐西昌吉自治州境内,全桥255.92m,由7孔24m和一孔16m预应力混凝土简支梁及一孔56m预应力钢筋混凝土拼装式系杆拱桥组成。主跨由铁道部第三设计院设计,第一工程局在1961年建成,同年由铁研院负责进行过静载鉴定试验。后该线因故停建,因此56m系杆拱桥,当时在国内国际上刚萌芽的这一新技术,没有
I. Overview Changji River 56m tied arch bridge is located in the Northern Xinjiang Urumqi Xichangji Autonomous Prefecture territory of the bridge 255.92m, the bridge consists of 7 holes 24m and a hole 16m prestressed concrete beam and 56m prestressed concrete one-hole assembly Arch bridge composition. The main span was designed by the Third Ministry of Railways Design Institute, the first engineering bureau was completed in 1961, the same year by the Iron Institute is responsible for static load test. After the line was suspended for some reason, so the 56m tied arch bridge, at the time just this new technology sprouting at home and abroad, there is no
