摘　　要：当前,地铁盾构隧道掘进过程中,为了使盾构机能够按照设计轴线掘进并按设计要求实现贯通,需要认真研究测量方案和方法,并对测量误差形成原因和隧道贯通精度进行估算分析,测算贯通时可能出现的最大偏差值,优选科学可行的测量方案和方法,确保隧道贯通的精度。本文以成都19号线牧高盾构区间右线为例,分析地铁盾构隧道贯通误差估算,以供参考。In the current process of subway shield tunnel excavation,in order to enable the shield machine to excavate according to the designed tunnel axis and achieve tunnel penetration according to the design requirements,it is necessary to carefully study and formulate measurement plans and methods,estimate and analyze the causes of measurement errors and tunnel penetration accuracy,calculate the maximum deviation value that may occur during penetration,select scientifically feasible measurement plans and methods,and ensure the accuracy of tunnel penetration.This paper takes the right line of the Mu Gao shield section of Chengdu Metro Line 19 as an example to analyze the estimation of tunnel penetration errors.
