摘要
提出了地铁工程圆形隧道断面测量的一种新方法。本文论述了地铁工程圆形隧道断面常规方法的测量过程,然后详细论述了采用新方法进行断面测量的过程,并推导了相关计算公式。最后以武汉市轨道交通四号线二期工程永安堂站~孟家铺站右线盾构区间为例,对两种方法求得的断面数据进行对比,表明在一般情况下采用新方法能满足规范要求。
This paper provides a new solution of measuring the cross section of subway circular tunnel.The article first discusses the measurement process of the conventional method,then introduces the method of how to fit the cross-section survey in detail,and the relevant calculation formula.Finally taking the shield tunneling section of Yongantang station to Mengjiapu station in the second phase of Wuhan Metro Line 4 as an example,the cross section data obtained by the two methods are compared,generally using the new method measurement can meet the standard requirements.
