测量塔定位系统在港珠澳大桥沉管安装中的应用

摘要

Based on the measuring tower positioning system of Hongkong-Zhuhai-Macao Bridge immersed tube installation, through the control installation and calibration, accuracy analysis, construction-location, total station instrument calibration, fast static detection, data processing, and breakthrough measuring review, we analyzed the successful application of measuring tower method in the construction of large-scale immersed tube installation in deep groove at deep water area. Proved by the engineering practice, the method can realize all-weather continuous operation, high positioning precision, strong reliability in real data. It is worth of popularization in accurate positioning and installation of large-scale components.%从港珠澳大桥沉管安装测量塔定位系统的安装及标定、精度分析、施工定位、全站仪校准、快速静态检测、数据处理、贯通测量复核等各环节，对测量塔法在深水深槽大型沉管安装中的成功应用进行分析，工程实践表明，该方法可以实现全天候连续作业，定位精度高，数据真实，可靠性强，在大型构件的精确定位安装中具有推广价值。
