测量作业指导书
1.编制依据
⑴《新建铁路工程测量规范》（TB10101—2009）； ⑵《全球定位系统（GPS）铁路测量规程》（TB10054）； ⑶《全球定位系统（GPS）测量规程》（GB/T18314—2001）； ⑷《国家一、二等水准测量规范》（GB12897—1991）； ⑸《国家三、四等水准测量规范》（GB12898-1991）； ⑹《铁路隧道监控量测技术规程》TB 10121一2007 ⑺《铁路隧道工程施工指南》（TZ204-2008）
2.执行标准
我分部管段设计为无砟轨道铁路，按客货共线列车设计行车速度120km/h，预留提速条件。该段铁路测量按以下标准执行：
⑴《国家一、二等水准测量规范》（GB12897—1991）； ⑵《国家三、四等水准测量规范》（GB12898-1991）； ⑶《新建铁路工程测量规范》（TB10101—2009）；
3.工程概况
南吕梁山隧道位于山西省临汾市境内，隧道线路贯穿于南吕梁山山脉以东及临汾盆地边缘丘陵区。隧道进口端位于蒲县境内，出口端位于临汾市尧都区及洪洞县交界处，设计为双洞单线隧道，线间距30m。1#斜井长2450m，2#斜井2630m。正洞承担里程段为DK301+285～DK310+800，位于直线段上，隧道内设计为单面坡，自洞口起分别以

无碴轨道铁路工程测量的平面、高程控制网，按施测阶段、施测目的及功能可分为勘测控制网、施工控制网、运营维护控制网。各阶段的平面控制测量应用共同使用一个GPS基础平面控制网。
无碴轨道铁路工程测量平面控制网按分级布网的原则分三级布设。第一级为基础平面控制网（CPⅠ），第二级为线路控制网（CPⅡ），第三级为基桩控制网（CPⅢ）。各级平面控制网的作用为：
① CPⅠ主要为勘测、施工、运营维护提供坐标基准； ② CPⅡ主要为勘测和施工提供控制基准；
③ CPⅢ主要为辅设无碴轨道和运营维护提供控制基准。
