摘要
随着高等级公路建设步伐的加快和沿江、沿海经济的快速发展,盾构隧道工程项目朝着大型化、综合化、复杂化方向发展,特别是大型越江跨海盾构隧道工程不断涌现,安全控制、环境影响控制和工期控制等要求越来越高,其中如何在长距离施工中保证大直径越江跨海隧道轴线精度成为施工关键,本文以目前世界上直径最大、同级别盾构机一次性掘进距离最长的盾构隧道-上海长江隧道工程为例,详细阐述高精度管片制作拼装、贯通测量及盾构姿态控制等隧道轴线精度控制的关键技术,并形成相应的三维轴线控制技术,为日后攻克更大、更长盾构隧道轴线控制给予借鉴意义。
With the accelerated pace of highway construction and the rapid development of economy along the fiver and coastal economy, the shield tunnel project is developing toward the direction of large-scale, comprehensive and complicated one, especially the emerging of large-scale cross-fiver or cross-sea shield tunnels, the safety control, environmental impact control, and increasingly demanding schedule control, including how to ensure the construction of large-diameter long-distance cross-fiver tunnel axis precision becomes the key problem in their construction. This paper takes the Shanghai Yangtze River Tunnel project as an example, which is a shield tunnel with the largest diam- eter and the longest distance of one-time tunneling by the same kind of shield machine in the world, the high-preci- sion segment production and assembly, linking measurement and shield tunnel axis attitude control and other precision control of key technologies are described and the corresponding three-dimensional axis control technology is formed, giving a lesson to shield tunneling with a larger diameter and longer axis of control in the future.
