摘要： 目前盾构法在地下隧道施工中应用的越来越多，曲线段隧道需要用标准环和转弯环配合拼装来满足设计轴线。曲线由一条圆曲线和两条缓和曲线组成，通过对设计轴线转弯角和转弯环管片的偏转角进行理论计算，从而确定管片排版计划；通过BIM技术建立盾构隧道3D模型，优化理论排版，并模拟隧道在施工过程中隧道的管片拼装质量及指导现场管片施工，使成型隧道轴线较好的附和设计轴线，确保隧道施工质量。

Abstract: At present shield tunneling method is applied more and more in underground tunnel construction. The standard ring and turning ring should be assembled to meet the design axis of curved section tunnel. The curve is composed of a circle curve and two relief curves, and the layout plan of the pipe sheet is determined by theoretical calculation of the turning Angle of the design axis and the deflection Angle of the pipe sheet in the turning circle. The 3D model of shield tunnel was established through BIM technology, and the theoretical layout was optimized. In addition, the assembly quality of tunnel segments in the construction process was simulated and the onsite construction of pipe segments was guided, so that the formed tunnel axis could better echo the designed axis and ensure the tunnel construction quality.
