隧道盾构推进施工影响轴线控制的原因和控制方法

Causes and Control Methods of the Shield Tunnel Construction Influencing Axis Control

作为隧道盾构掘进的重要技术手段,盾构隧道轴线控制的精确度,对隧道施工具有直接的影响,譬如轴线偏移,会影响管片的拼装,严重时会产生过大的施工荷载,从而引起管片开裂。本文将在对隧道盾构推进施工影响轴线控制原因分析的基础上,对如何控制轴线的方法展开深入探讨。

As an important technology in the shield tunnel construction, shield tunnel axis control accuracy, has direct influence on the tunnel construction, such as axis skewing, wil affect the pipe instal ation, seriously can produce heavy construction load, causing the segment cracking. In this paper, based on the analysis of the causes of shield tunnel construction influencing axis control, discusses the method of how to control the axis.
