摘要
竖井间贯通测量是地铁隧道施工的重点和难点,因而探索适合城市地铁工程特点的贯通测量技术措施至关重要,本文根据隧道贯通测量的基本工艺流程,在分析贯通测量主要误差源的基础上,对联系测量和地下导线测量两个重要环节进行误差分析和精度预估,提出了适合青岛地铁自身实际的测量精度保证措施,通过实际工程验证,取得了较好的效果。
The shaft piercing measurement is the key and difficult point in the subway tunnel construction,and exploring the essential measures through suitable for city subway engineering is important,according to the basic process of tunnel measurement,based on the analysis of the main error sources through measurement,this paper implies error analysis and accuracy prediction on measurement of contact and underground traverse and proposes measurement accuracy for Qingdao Metro actual measures.Good results are achieved through practical engineering.
