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
隨著國家經濟的發(fā)展和環(huán)保意識的提高,隧道在工程建設中的應用越來越多,尤其在高等級道路中,可以充分發(fā)揮避免山體開挖,減少施工及運營期病害,提高道路整體通行效率等優(yōu)點。(剩余3649字)
