摘要
阐述了盾构工作原理,分析了竖井定向的主要误差来源,以忠武输气管线红花套长江穿越盾构隧道工程为实例,运用GPS、精密工程测量、陀螺仪定向等工程测量检测方法,保证了忠武输气管线红花套长江穿越盾构隧道的贯通。
In this paper, we described the working principle of shield construction and analysed the errors in the vertical shaft direction. With example of the Honghuatao Shield Tunnel under Yangtsz River in ZhongxianWuhan gas conduit project, to ensure the connecting of Honghuatao Shield Tunnel under Yangtse Rive in Zhongxian-Wuhan gas conduit project by the engineering survey and detect methods such as GPS, precision engineering survey, gyro-orientation etc.
