黑龙江工程学院本科生毕业设计摘要本设计是青海路地下商业街设计。青海路全长较长，整条路呈不规则分布，有拐角路宽24米，两侧为住宅和商场等建筑，建筑物呈规则分布。地基土主要是粉土、杂填土粘土等。本设计选取青海路一段直线段下建设商业街，拟建商业街全长304米，商业街宽24米。本设计地下部分采取的是框架柱网式设计，为8米×8米柱网。根据最不利荷载组合对框架结构进行内力分析，通过内力分析知道框架结构各个关键处的弯矩和轴力，根据轴力来进行顶板、侧墙、和底板的配筋，同时对个出入口的楼梯进行截面的配筋和内力计算，进行楼梯处设计，最后结合当地的施工条件对地下商业街进行施工方案的选择。设计的主要内容有结构设计、建筑设计、楼梯进出入口设计、通风照明设计、和施工方案设计。符合相关规定和适用要求，设计方案可行。关键词：最不利荷载；框架结构；施工方案；结构设计；内力分析I黑龙江工程学院本科生毕业设计ABSTRACTThisdesignisthedesignoftheundergroundbusinessstreetoftheQinghaiRoad.QinghaiRoad’stotallengthismuchlonger.Theentireroadtotheirregulardistributionofthecorner,andlane24metersonbothsidesoftheresidentialandshoppingmallsandotherbuildings.Thebuildingwasuniformlydistributed.Thefoundationsoilismainlysilt,miscellaneousfill,andclay.ThedesignisselectedastraightlineunderconstructionCommercialStreetofQinghaiRoad.Thelengthofthecommercialstreetis304metersandthewideis24meters..Takenbytheundergroundpartofthisdesignisanintensivedesignoftheframecolumn8m×8mcolumngrid.Accordingtothemostunfavorableloadcombinationanalysisoftheframeworkstructureoftheinternalforce,internalforceanalysistoknowtheframeworkstructureofeachofthekeyatthemomentandaxialforce.Axialforcetothereinforcementoftheroof,sidewalls,andfloor,thestairsandentrancescross-sectionofthereinforcementandinternalforcecalculation,stairsdesign,andfinallycombinedwiththechoiceofthelocalconstructionconditionsundergroundcommercialstreetconstructionprogram.Themaincontentofthedesignofthestructuraldesign,architecturaldesign,thestairsintotheentrancedesign,ventilationandlightingdesign,andconstructiondesign.Complywiththerelevantprovisionsandtheapplicablerequirements,thedesignisfeasible.Keywords：TheMostUnfavorableLoad；FrameStructure；ConstructionProgram；StructuralDesign；InternalForceAnalysisII黑龙江工程学院本科生毕业设计目录摘要.........................................................................................................................................IABSTRACT.........................................................................................................................II第1章绪论..........................................................................................................................11.1选题目的和意义..................................................11.2国内外发展现状..................................................11.3设计的基本内容及拟解决的主要问题................................41.3.1具体完成的设计内容有：..........................................................................51.3.2技术要求......................................................................................................6第2章建筑设计................................................................................................................72.1概述............................................................72.2平面柱网选择....................................................72.3建筑方案的选择..................................................82.4建筑平面设计............
