摘　　要：该文在总结隧道建筑限界及内轮廓设计过程中存在问题的基础上,提出基于隧道设计规范要求及工程应用的隧道建筑限界分步旋转拟定方法,明确隧道内轮廓与建筑限界最小间距要求,继而确定隧道内轮廓。通过隧道标准化设计为标准化施工提供设计基础,具有一定的推广价值。On the basis of summarizing the problems existing in the design of tunnel construction clearance and inner contour,this paper puts forward a step-by-step rotation formulation method of tunnel construction clearance based on tunnel design code and engineering application, and defines the minimum spacing requirements between tunnel inner contour and construction clearance, then determine the inner contour. The standardized design of tunnel provides the design basis for standardized construction, which has a certain promotion value.
