温州市大门大桥主塔施工测量技术

介绍大门大桥主桥加密控制网情况,分析大桥主塔的测量定位控制技术、方法及精度,采用相对基准三维极坐标法和相对基准差分三角高程法进行塔柱平面及高程的测量放样,实践表明,其测量精度和放样误差完全满足相关规范的要求。该法方便易行,保证工程施工质量,且加快工程施工进度,对今后海中高塔柱施工建设的测量工作具有一定的借鉴意义。

Construction Survey Technology of Main Tower of Wenzhou Gate Bridge

Based on the simple introduction of the Gate Bridge encryption control network situation,mainly describes the measurement location bridge main tower control technology,method and precision analysis,measurement and control relative datum 3Dpolar coordinate method and relative standard difference by means of trigonometric leveling plane and elevation of the tower,the precision of measurement and lofting error fully meet the requirements of relevant standards.Practice shows that,this method is convenient,but also to ensure the construction quality,and speed up the progress of project onstruction,has certain reference significance to construction of tower column measurements in the future of the sea.
