摘　　要：以成都市二环路北新立交高架桥整体顶升改造工程为例,介绍了桥梁同步顶升技术在城市立交改造工程中的应用,重点阐述了桥梁同步顶升技术的监测内容及测点布置方案,监测结果均满足要求。为多跨简支体系桥型整体顶升加固工程提供了一定的参考,同时也为相关工程改造设计及施工提供了有益经验。Taking the reconstruction project of Bei Xin interchange viaduct in the second ring road of Chengdu as an example,bridges synchronous jack-up technique in the application of the city overpass project are introduced,which focuse on the monitoring of bridge sync jack-up technique content and layout of measuring points. The monitoring results meet the requirements. The multi-span simply supported girder bridge integrally jack-up provides certain reference for engineering,as well as provides the useful experience for relevant engineering design and construction.
