地铁工程施工测量的施测环境和条件复杂,要求的施测精度又相当高,必须精心施测和进行成果整理,工程测量成果必须符合相关规范的要求。地铁工程测量的测量特点(1)车站包括主体结构、出入口和风道。采用明挖及盖挖顺作法施工方法,施工工艺复杂,工序转换快,地下施测条件差,测量工作量大。
The construction environment and conditions for the subway construction survey are complex, and the required measuring precision is rather high. Therefore, it is necessary to carefully test and organize the achievements so that the engineering measurement results must meet the requirements of relevant norms. Subway engineering measurement measurement characteristics (1) The station includes the main structure, entrances and exits and air duct. The method of open dig and cover digging is adopted, the construction technology is complex, the process is changed quickly, the conditions of underground survey are poor, and the measurement workload is heavy.
