近几年随着城市建设的快速发展,从适应现代化城市环境需求来考虑,在建筑设计中既要满足使用功能要求,又要注重建筑外观造型,许多外观造型复杂及测量精度要求较高的高层建筑物应运而生,在这些建筑工程施工过程中,测量工作尤为显得重要。测量放线是建筑工程施工的重要环节,它是按照设计要求配合施工进度测出地平面位置和标高,是 In recent years, with the rapid development of urban construction, in order to meet the needs of the modern urban environment, it is necessary to meet the functional requirements in the architectural design, but also pay attention to the appearance of the building, many complex exterior appearance and high precision measurement requirements Buildings came into being, the measurement work is particularly important in the construction process of these buildings. Measuring line is an important part of the construction of the building, which is in accordance with the design requirements with the construction schedule to measure the ground plane position and elevation, is
