1、结合实例论述建筑施工测量放线的方法摘要:本文具体对某工程的施工测量放线方法进行论述，提出相关实践经验以供参考。关键词:测量放线;轴线测设;基坑验线1工程概况某工程的建筑总高度为68.88m,共有18层。其中地下室有一层,层高为4.2m,地上一层的层高为5.4m,地上2、3层层高为5.1m。地上3层为裙房,塔楼以4层开始至16层,标准层层高为3.3m。整个建筑平面呈长方形,结构类型属于现浇框筒结构。设计要求测量的精度为:垂直度≤15mm,控制轴线位移1/10000。2施工准备首先要对建筑的工程图纸进行
2、自审和会审工作，了解工作全貌和主要设计意图,着重了解工程现场情况和定位条件,主要建筑物的相互关系和轴线尺寸、标高以及测量精度。然后准备好测量的仪器，并对此测量仪器作一次检定校正。设置测量轴线及控制点，控制点设在建筑物以南永久的控制桩上,其顶标高即为本建筑物的±nthemainterminal,andthetelephoneOfficeisresponsibleforprovidingtheappropriatesizeadapterpatchpanelsandelectricalprotection
