| 摘 要： | 以狮子洋盾构隧道为例,探讨了在长距离水下盾构隧道施工中,采取从两端相向施工,地中对接方案时施工测量方法的优化.从施工测量项目统筹规划、贯通精度要求设置、地面控制测量方法、联系测量方法、地下测量方法和盾构导向测量方法等方面给出了优化方案,隧道的顺利贯通表明采用该测量方案可以满足长距离盾构隧道最终贯通精度的要求.

| Abstract: | Taking Shiziyang Tunnel as an example, the paper discusses the optimization methods of the long distance underwater shield tunnel construction, which adopts the docking underground methods from opposite ends of the project. Optimization plan include measuring project construction plan as a whole, transfixion precision requirement, ground control survey, connection survey, underground control survey and tunnel guiding survey. Successful connecting of the tunnel means that the method can satisfy the transfixion precision requirement of the tunnel. |
