摘　　要：本文以济宁市龙拱河特大斜拉桥为项目基础,通过对城市斜拉桥索塔爬模施工方式的创新,实现仅需一次架体转换完成主塔施工全过程,有效降低了爬模的转换次数,发挥液压爬模在施工中的高效性。同时通过对监测平台采集和存储的数据进行分析,分析结果表明构建的监测平台能实现城市桥梁监测数据的有效性、实时性和同步性,更能适合我国国情和具体养护技术人员的实际操作。在保证施工安全的前提下,提高施工效率,减少施工成本,可为类似工程提供施工经验。With Jining Longgonghe Cable-stayed Bridge as anchor point,through the innovation of urban cable-stayed bridge tower climbing mode construction,the whole construction process of the main tower can be completed with only one frame conversion,which effectively reduces the number of climbing mode conversion and gives play to the high efficiency of hydraulic climbing mode in construction.At the same time,through the analysis of the data collected and stored by the monitoring platform,the analysis results show that the constructed monitoring platform can realize the effectiveness,real-time and synchronization of the monitoring data of urban bridges,which is more suitable for the actual operation of China's national conditions and specific maintenance technicians.Under the premise of ensuring construction safety,this model can improve construction efficiency and reduce construction cost,which could provide construction experience for similar projects.
