摘要
在工程测量中,根据测图和施工放样的要求选择投影面和投影带,确立工程平面控制网的坐标系。针对铁路工程不同特点,从控制投影变形、计算方便和施工放样等方面优化测量方案,确保测量精度。
The choice of plane of projection and projection zone based on mapping and setting out and establishment of engineering plane control network for coordinate systems are important subjects in engineering survey.Aiming at the characteristics of railway engineering,the survey plan is optimized from the control of projection deformation and convenient calculation and setting up in order to ensure the accuracy of survey.
