| Abstract: | 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. |
