摘要
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。
Xianyue West Road reconstruction project is a key project of Xiamen City. The lift-up re- construction of five overpass bridges, including Hudong Road Overpass Bridge, Fuxia Road Overpass Bridge and Lianyue Road Overpass Bridge etc. ,is first and foremost important, because its success or not is directly related to the reconstruction and continued construction project completed on time and the resul- ting social impact. The five Overpass Bridges have their own characteristics.three of them are prestressed concrete box beam girder, the others are steel box beam girder. The Hudong Road overpass bridge is a curved box girder,its lift-up weight heaviest and height of lift-up is the highest in China now. Therefore, this project＇s construction and monitoring is extremely difficult. Thus developing a detailed and feasible construction and monitoring plan is the key to the smooth completion of the project. Depending on Xianyue West Road reconstruction project＇s in Xiamen City, some difficulties encountered in the specific process of lift-up construction and monitoring are summarized, as well as some problems noted in construction and monitoring are point out,a reference to similar projects is provided.
