摘  要:平潭海峡公铁两用大桥共3座斜拉桥6个主塔,为满足斜拉桥索导管及钢锚梁定位精度要求,需对主塔日照变形和风力变形进行系统监测,得到主塔日照及风力变形规律,从而确定索导管、钢锚梁安装测量的最佳时段及最大风力等级。基于徕卡TM30测量机器人ATR自动照准技术,开发出主塔自动监测软件及数据处理软件,方便、快捷、准确、自动地进行主塔变形监测及数据分析处理。Pingtan Strait highway-railway dual-purpose bridge has 3 cable-stayed bridges and 6 main towers.In order to meet the positioning accuracy requirements of cable ducts and steel anchor beams of the cable-stayed bridge,it is necessary to systematically monitor the sunshine deformation and wind deformation of the main tower to obtain the law of sunshine and wind deformation of the main tower,so as to determine the best period and maximum wind scale for the installation and measurement of cable ducts and steel anchor beams.Based on the ATR automatic alignment technology of Leica TM30 measuring robot,the main tower automatic monitoring software and data processing software are developed,which are convenient,fast and accurate,and can automatically conduct main tower deformation monitoring and data analysis and processing.
