橋梁畢業(yè)設計摘要

摘要隨著中國經濟的騰飛，公路隧道工程也得以迅猛發(fā)展，隧道長度越來越長，斷面尺寸越來越大，修建技術和營運技術日趨復雜，一般都建于峽谷和丘陵等地帶之中。地形地質條件復雜，對公路又提出更高的要求。本論文結合丹海高速公路，對羅圈背隧道工程的實施方案的優(yōu)化關于其設計技術、施工技術、施工組織和施工方案的技術經濟性能進行了較全面深入的研究。本文針對羅圈背隧道修筑中存在的問題進行研究，其隧道長1950m，設計洞身寬11.73m,,洞高7.5m.入口段及出口段為V、W級圍巖，洞身段為III、II級圍巖設計兩條單行曲線隧道。本文在對工點范圍內的地形、地質及水文條件等外業(yè)資料詳細勘測的基礎上，參考《公路隧道設計規(guī)范》、《公路隧道施工技術規(guī)范》《隧道工程》《地下結構靜力計算》以及以及其他工程設計經驗，對該隧道進行了較系統(tǒng)的設計和施工方法研究，全文共八章。主要有隧道基本情況說明（線路情況、隧道所處地質條件、地形條件等）隧道洞身設計、隧道內附屬工程設計、隧道施工組織設計等。本文對隧道的施工方式進行詳細的說明：光面爆破、一次襯砌、二次支護、防水、通電。本文中對不良地質災害的預測及防治措施也進行研究如巖爆的預測與防止和隧道圍巖失穩(wěn)及施工對策，在施工監(jiān)測方面利用探地雷達檢測地下工程襯砌質量，大大減少空區(qū)、空段、塌方。本文對隧道的施工組織設計進行了詳細研究，對洞身開挖、襯砌等重要工序提出了詳細工藝流程。本文的設計施工方法對丘陵地區(qū)隧道工程有重要參考價值。關鍵詞：公路隧道；圍巖；爆破；施工組織AbstractWiththeeconomictakeoffofChina,highwaytunnelprojecthasbeentherapiddevelopmentofincreasinglylongtunnellength,crosssectionsizeincreases,theconstructionofincreasinglycomplextechnologyandoperationaltechniquesgenerallybuiltinthevalleysandhillsamongotherareas.Topographicandgeologicconditionsarecomplex,ontheroadhasputforwardhigherrequirements.ThisthesisDanhaihighwaytunnelprojectbackontheRomanianSpaceOptimizationoftheimplementationoftheprogramonitsdesign,constructiontechnology,constructionorganizationandconstructionprogramoftechnicalandeconomicperformanceofamorecomprehensivestudy.Inthispaper,bandybackproblemsinthetunnelconstructionofresearch,thetunnellength1950m,widebodydesignhole11.73m,,holehigh-7.5m.EntranceandexitoftheV,IVgraderocks,holesfiguretoIII,IIsinglecurvesurroundingthetwo-leveldesignofthetunnel.Thisworkpointsintherangeoftopography,geologicalandhydrologicalconditionsloadedwithindustryinformationonthebasisofdetailedinvestigation,referto"tunneldesign","TechnicalSpecificationforConstructionofHighwayTunnel,""tunnelproject","staticanalysisofundergroundstructure"andaswellasotherengineeringdesignexperience,themorethesystemofthetunneldesignandconstructionmethod,thefulltextofeightchapters.Therearebasicconditionsofthetunnelshows(linecondition,thetunnelthegeologicalconditions,terrainconditions,etc.)tunnelandbodydesign,ancillaryworksinsidethetunneldesign,tunnelconstructionorganizationdesign.Thismethodoftunnelconstructiondetailedinstructions:smoothblasting,alining,secondarysupport,water,electricity.Badarticleonpredictionsandgeologicaldisasterspreventionmeasuresarealsostudied,suchaspredictionandpreventionofrockburstandrockfailureandtheconstructionofthetunnelmeasuresusedintheconstructionmonitoring,ground-penetratingradardetectionofundergroundengineeringliningquality,greatlyreducingthegap,spacesegment,landslides.iiiiiiInthispaper,theconstructionofthetunnelforadetailedstudyoforganizationaldesign,excavationofthetunnelbody,liningandotherimportantdetailsofproposedprocessflow.Thismethodofdes
