广东九江大桥换索工程研究
|
摘要
近些年来，斜拉桥在我国得到了迅速发展。在不到30年的时间里，我国已建和在建的斜拉桥已近百座。然而，斜拉桥的防腐问题一直是世界性的难题，并对斜拉桥的耐久性构成了严重的威胁。在今后相当长的一段时间内，防腐问题还将继续存在。因而，对斜拉桥的换索做一些研究，是有一定的意义的。本文以广东九江大桥为背景，对斜拉桥的换索进行了一些探讨。论文由以下几部分构成：首先对斜拉桥的发展历程做了简要的回顾，然后介绍了九江大桥的换索施工，接下来通过详尽的理论计算，提出了合理的调索施工方案，不但节约了时间和人力，并收到了良好的效果。最后，文中还对九江大桥的监控提出了建议。九江大桥在国内首次实现了在不中断交通的情况下完成换索，成功地实现了部分调索。这对于今后类似的换索工程，有一定的借鉴作用。
In recent years, the construction of cable-stayed bridges has been experiencing a rapid development. Within the past 3D years, there have been nearly 100 cable-stayed bridges completed or under construction in China. However, the anti-erosion of the cables is still a worldwide difficult point, and it will continue to be a problem for a long time. Consequently, research on the replacement of cables becomes somewhat significant. Based on the replacement of cables of the Guangdong Jiujiang Major Bridge, some research on this problem was performed. This thesis includes several parts as follows: First, a brief review of the development of the cable-stayed bridges was made. Then, the process of cable replacement of the bridges was introduced. Next, after a detailed theoretical analysis, a proper method of adjusting cable-force, which was not only time- and labor-saving, but also accurate enough, was determined. Finally, in the last part of the thesis, the author also puts forward some suggestions on the long-term
monitoring of the bridge. The replacement of the cables of the Guangdong Jiujiang Major Bridge was carried out under a circumstance of no traffic interruption, setting a record in our country, and the idea of partial adjustment of cables also proved successful, both of which may provide some valuable experience for the repair of similar bridges.
