厦门市仙岳路西段改造工程是厦门市的重点工程,其中湖东路口跨线桥、福厦路口跨线桥、莲岳路口跨线桥共5座跨线桥的顶升改造更是重中之重,其成败直接关系到改造续建工程能否按时竣工以及由此带来的社会影响。5座跨线桥各具特点,其中3座为预应力混凝土箱梁桥,2座为钢箱梁桥。湖东路第五联跨线桥顶升工程为国内最重、顶升高度最大的弯箱梁,施工与监控的难度极大,因此制订详细可行的施工、监控计划是工程能否顺利完成的关键。根据具体的顶升施工与监控过程中遇到的一些难点加以总结,提出一些施工及监控中应注意的问题,给同类工程提供参考。
Xiantao Road, Xiamen City, the western section of the renovation project is a key project in Xiamen City, of which Hudong Junction, Flyover crossings bridge, Lin Yue intersection jumpers a total of five flyover upgrade is more important Its success or failure is directly related to the timely completion of the reconstruction and reconstruction project and the social impact it brings.
