摘要
在重大建筑物施工控制中，放样方法本身的精度估算及分析是制定测量方案的重要依据。结合番禺大桥索塔施工实践，讨论极坐标法施工放样完整、合理的精度评定方法。通过精度估算与分析，认为采取一定措施后，极坐标法能较好地完成番禺大桥索塔施工控制的任务。
In construction of important and large buildings, a precision estimation and analysis of layout method are important data for working out survey plan. Incorporated with experiences in construction of cable pylon of Panyu bridge, a method to fully and reasonably estimate the precision of polar coordinate layout is discussed. Based on the discussion,it is believed that polar coordinates can be used for construction control of cable pylons of Panyu bridge, provided certain precautions are taken.
