摘 要:該文在總結(jié)隧道建筑限界及內(nèi)輪廓設(shè)計(jì)過(guò)程中存在問(wèn)題的基礎(chǔ)上,提出基于隧道設(shè)計(jì)規(guī)范要求及工程應(yīng)用的隧道建筑限界分步旋轉(zhuǎn)擬定方法,明確隧道內(nèi)輪廓與建筑限界最小間距要求,繼而確定隧道內(nèi)輪廓。通過(guò)隧道標(biāo)準(zhǔn)化設(shè)計(jì)為標(biāo)準(zhǔn)化施工提供設(shè)計(jì)基礎(chǔ),具有一定的推廣價(jià)值。
關(guān)鍵詞:隧道;建筑限界;內(nèi)輪廓;旋轉(zhuǎn);標(biāo)準(zhǔn)化

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(guó)家經(jīng)濟(jì)的發(fā)展和環(huán)保意識(shí)的提高,隧道在工程建設(shè)中的應(yīng)用越來(lái)越多,尤其在高等級(jí)道路中,可以充分發(fā)揮避免山體開(kāi)挖,減少施工及運(yùn)營(yíng)期病害,提高道路整體通行效率等優(yōu)點(diǎn)。(剩余3649字)
