大型斜拉桥超高塔控制测量技术设计与实践
|
摘要
以在建的武汉四环线青山长江大桥为例,针对大型斜拉桥超高塔复杂结构高精度控制测量特点,按照绝对控制与相对控制分阶段测量的思路,系统研究了斜拉桥超高塔平面工作基准点竖向传递的主要测量方法及误差大小,最终确定"全站仪天顶测量+全站仪短距极坐标测量"为超高塔锚固件定位测量方案。工程应用表明,该方案满足施工精度要求,对其他类似工程有重要参考价值。
Taking the on-going Qingshan Yangtze River Bridge as the example which is a large cable-stayed bridge with super-high pylons and complex structure requiring hi-precision controlling survey,main survey methods and error range related to the vertical transfer measurement of super-high pylon plane datum points are studied systematically in the paper,according to the principle of absolute control and relative control measurement in various stages. Finally,the proposal of total station zenith measurement and total station polar coordinate measurement for short distance is determined as the measurement plan of the anchoring parts location. The application shows that the plan can meet the requirements of construction precision and provide important reference for other similar projects.
