隧道工程专业毕业设计摘要.doc

摘要从襄樊到安康的元和观一号隧道是一条短隧道。本次设计题目为元和观一号铁路隧道设计，隧道总长101m。根据工程地质资料进行隧道的平、纵断面设计；参照规范和洞门标准图，确定洞门类型，利用作图法确定洞口位置和洞口边、仰坡开挖线；利用挡土墙原理进行洞门结构检算，包括翼墙与端墙的强度及稳定性检算；根据隧道围岩类型和等级进行衬砌设计，确定衬砌形式，计算隧道的围岩压力，利用FORTRAN程序进行衬砌的内力计算，此外还利用自编FORTRAN程序检算二衬的强度；参照隧道施工方法及有关的施工方法的资料，确定其采用台阶法施工，对元和观一号隧道进行施工组织设计。关键词：隧道洞门衬砌设计开挖施工 AbstractTheNO.1tunnelofYuanHeguanontherailwayfromXiangfantoAnkangisashort-longrailwaytunnel.DesigntopicisthedesignfortheNO.1ofYuanheguantunnel,thetotallengthofthetunnelis101m.Theplanesection&verticalsectionofthetunnelareexecutedaccordingtotheengineeringgeologymaterial.Basedonthenorm&theholeastandarddiagram,thegatetypeofthetunnelisascertained.Thepositionoftunnnelportalandthepaylineoftunnelareconfirmedmakingusethemethodindiagram.Thecalculationoftunnelportalisproceedfoundingontheretainingwallprinciple,comprisingthestrengthandstabilitycalculationofthewing&breastwall.Liningisdesignedaccordingtothetypeandgradeoftunnelsurroundingrock,anditsformisascertained.Thetunnelroundthesurroundingrockpressureiscomputed.TheinternalforceofliningisproceedinthelightofFORTRAN.Additionally,thestrengthofsecondaryliningiscalculatedgroundingontheplaitFortranprocedure.Basedonthetunnelconstructionmethodandthematerialoftheconstructionmethod,Stepmethodisadopted.TheconstructionorganizesoftheYuanheguantunnelisdesigned.Keywords:tunneltunnelportalthedesigningofliningExcavateConstruction X
