摘　　要：以哈大客运专线运粮河特大桥为例,介绍了目前我国铁路施工中,跨径最大、结构最重要的转体工程施工监测技术。为保证施工监测的科学性,首先对钢箱叠合拱桥进行了仿真分析,施工及其监测过程通过计算设计图与实测相结合的方式推进。在施工中完成了预压和运梁过程中结构的变位、应力(应变)和温度控制与监测,大型临时工程钢管支架的应力和位移监测。Based on Yunliang River Bridge in Harbin-Dalian passenger dedicated line,the authors introduce construction monitoring technology for horizontal rotating engineering of continuous girder with the longest span and the most important structure.In order to ensure the science for construction monitoring,the authors simulate and analyze steel box stacked tied arch bridge,the construction and monitoring process are promoted by calculation design drawing combined with measurement.The control and monitoring of structure displacement and stress（strain） and temperature is completed in construction,the stress and displacement monitoring of steel pipe support for large temporary engineering are completed in construction.
