摘要
在施工中 ,施工放样的准确性对整个工程的质量起着关键性作用。施工图纸中 ,并不一定给出每点的坐标 ,还需要经过施工人员计算才能得出。介绍北京 5
During construction, the accuracy of construction lofting is an decisive factor for the quality of the whole project. Coordinate of each point is not necessarily given in construction drawing, sometimes it will be obtained through calculation. The formula derivation of Beijing 54 coordinate system and corresponding calculation example are introduced.
