无支架缆索吊系统的设计与施工

Design and Construction of Rope Hoisting System in Pipe Arch Bridge

根据浙江千岛湖1号桥主桥缆索吊装系统的设计与施工的各个环节的实施情况,对吊装系统的主塔布置,主索系统,地锚,风缆等根据现场条件和施工条件进行设计,并根据各部件受力情况从工程安全的角度进行设计优化改善了结构的受力性能。对该桥的缆索吊装系统进行了总结与分析,可为类似的钢管拱桥吊装工程施工提供一定参考价值。

According to the Qiandao lake in Zhejiang on the 1st bridge rope hoisting system design and construction of all aspects of the implementation of the system for loading layout of the main tower, the main cable systems, anchors, cables, etc. According to the wind conditions at the design and construction conditions, subject to and in accordance with parts of the security situation from the perspective of engineering design optimization to improve the structure of the force. Hoisting the bridge cable system has been up and analysis, for a similar hoisting steel pipe arch bridge construction to provide a reference value.
