本設(shè)計為五海公路青龍山隧道隧道設(shè)計。該隧道地處撫遠(yuǎn)縣境內(nèi)境內(nèi)，為直線型分離式單向行駛二車道長隧道（上、下行分離）。上行隧道樁號 K257+～ K259+（其中明洞 ，暗洞 1526m），全長為 ；下行隧道樁號 K257+～K259+（其中明洞 ，暗洞 ），全長為 ；隧道最大埋深 ，所處圍巖等級為Ⅳ級；隧道縱坡采用單向坡，坡度為 %；該隧道襯砌采用復(fù)合式襯砌，斷面形式為曲墻拱形斷面；洞門為端墻式洞門；明洞與暗洞襯砌形式相同，明洞采用明挖法施工，暗洞采用新奧法施工；隧道的通風(fēng)和照明設(shè)計內(nèi)容按照行車速度80km/h 設(shè)計。 本次設(shè)計的主要內(nèi)容包括：隧道選址、隧道平縱橫設(shè)計、洞門與明洞設(shè)計、襯砌與支護設(shè)計、 施工方案設(shè)計、防排水設(shè)計、通風(fēng)照明設(shè)計等。 經(jīng)驗算，該隧道設(shè)計合理，方案可行，滿足撫遠(yuǎn)縣公路的服務(wù)水平。 關(guān)鍵詞 ：隧道；襯砌；明洞；洞門；新奧法。 黑龍江工程學(xué)院本科生畢業(yè)設(shè)計 II ABSTRACT The design for the Qinglong hill
