Abstract: 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.

Keywords: tunnel; building limit; inner contour; rotation; standardization

随着国家经济的发展和环保意识的提高,隧道在工程建设中的应用越来越多,尤其在高等级道路中,可以充分发挥避免山体开挖,减少施工及运营期病害,提高道路整体通行效率等优点。(剩余3649字)
