重庆市朝阳复建桥缆索吊装方案分析

The cable hoisting system in the reconstruction of Chaoyang Bridge in Chongqing

由于现场设计环境发生重大变化,重庆市朝阳复建桥在建设过程中对大桥缆索吊装系统优化前后的3种方案进行比选和论证。结果表明:优化后的缆索吊装系统不仅有效地解决两岸地形限制和玻璃厂房拆迁的难题,而且更加安全、经济、合理。重点介绍大桥缆索吊装系统的主要比选方案,进一步论证缆、扣塔一体化吊装体系的优越性,旨在为今后同类型桥梁的建设提供工程借鉴和设计参考。

As the great changes result from the environment designed, three installation schemes have been selected and demonstrated in the reconstruction process of the Chaoyang Bridge in Chongqing. The results indicates that the optimized cable hoisting system not only release the terrain limit and the difficult of pulling down the glass workshop, but is safe, economical and reasonable. Analysis is made on introducing the plans selected of cable hoisting system in order to prove the superiority of the hoisting structural system of an integrated installation of cable tower and buckle tower, which will provide a reference for future bridge construction.
