摘　　要：城市轨道交通主要规划在城市的主城区,经常遇到深度较大、场地狭小的竖井,此时无法通过导线直接将坐标和方位传递到地下,而一井定向和两井定向测量方法则能发挥重要作用。本文以南宁地铁3号线青秀山站~市博物馆站区间为研究对象,详细阐述了一井定向和两井定向联系测量方法在长区间、深竖井条件下的作业要求、精度控制方法以及注意事项,并对青秀山站~市博物馆站区间联系测量的次数进行了确定和结果做了分析。保证了青秀山站~市博物馆站区间贯通,可为其他城市的类似工程提供借鉴。Urban rail transit is mainly planned in the main urban area of the city,often encountering deep and narrow vertical shafts.At this time,coordinates and directions cannot be directly transmitted to the underground through wires.However,one well directional and two well directional measurement methods can play an important role.This article takes the section from Qingxiushan Station to Municipal Museum Station of Nanning Metro Line 3 as the research object,and elaborates in detail on the operational requirements,accuracy control methods,and precautions of one well directional and two well directional connection measurement methods under long and deep vertical well conditions.The frequency of connection measurement between Qingxiushan Station and Municipal Museum Station is determined and the results are analyzed.This ensures the connectivity between Qingxiushan Station and the Municipal Museum Station,which can provide reference for similar projects in other cities.
