毕业设计——船闸工程设计

I东沟船闸改造工程设计学号：姓名：指导老师：摘要近年来，上海港发展较快，为了提高水路集疏运的能力，急需开辟水上运输的新通道。采用船闸进行改进。根据预测的货运资料和当地的自然条件，船闸的总尺度为240m×24m×4.5m。引航道采用不对称式布置，直线段总长840m。由于水头差较小，故采用三角闸门门缝输水，也便于在船闸运行期间可能会采用通闸过船。为了限制中缝宽度提高闸室内的船舶稳定，因此选用中心角为80的三角闸门。为了避免边羊角处的回旋水流增大启闭机的功率，通过方案比选，门库采用加有导流鼻槛的开敞式门库。通过水力计算求得了闸室灌泄水时的水力特性曲线，以及校核闸室和引航道内的泊稳条件。闸室采用不透水底板，闸室墙与导航墙均采用重力式空箱结构。选用第一种使用情况下的荷载，对闸室进行了稳定性验算，并对底板进行内力了计算,并根据内力计算结果进行了配筋计算。关键词：船闸；设计；东沟；配筋IITheDesignofReconstructiveProjectofDongGouShiplockNum:Name:Supervisedby:AbstractAtpresent,theportofShanghaidevelopedmorefast.Inordertoincreasetheamountofcargoornumberofpassengersconveyedbywaterway,it'saimminencetoinauguratenewchannels.Ashiplockwillbebuilt.Accordingtotherognosticateofthefreightandtheconditionofthenature,thesizeoftheshiplockis240m×24m×4.5m.Theformofapproachchannelissymmetry,andthelengthofthebeelineis840m.Onaccountofthemarginofthewaterlevelofthetwosidesislittle,maketheuseofthepeekedofthecamberedgatetoaqueduct.It'sconveniencefortheshipsthroughtheshiplockbystraight.Toconfinethewidthofthemiddleslotandimprovethestabiliz-ationoftheshipsinthechamber,thecenterpointofthegateisselectedas80degree.Toavoidtheroundaboutcurrentaugmentthepowerofthehoist,theroomageisdesignedaopenformwithanasalenclosuresfordiversion.Thecurveofthecharacte-risticsofhydraulicisobtainedasaresultofhydrauliccalculate,andtheconditionoftheparkstableinthechamberandapproachchannel.Thechamberismotherboard.Thewallofthechamberandapproachchannelistheframeofgravityandempty.Choosetheloadofthefirstsituationforoperationtocalculatethestabilityofthechamber.Andtocalculatetheinternalforceofthemotherboardofthefirstshiplockhead.Basedontheresultoftheinternalforce,thereinforcingsteeliscollocatedinthelightofthestandardofthemassconcrete.Keywords:shiplockdesignDonggoucollocatesteel目录摘要...........................................................................................................IAbstract......................................................................................................II第一章总论...............................................................................................11.1工程概况..........................................................................................................11.2工程可行性与必要性......................................................................................11.3设计规范及标准..............................................................................................21.4经济状况及自然条件......................................................................................2第二章船闸总体规划和布置..................................................................42.1船闸规模...........................................................................................................42.1.1闸室有效尺寸.........................................................................................42.1.2各部分高程.............................................................................................52.1.3引航道型式及尺度.................................................................................52.2船闸的通过能力..............................................................................................6第三章输水系统的设计..........................................................................93.1输水系统的选择..............................................................................................93.2启闭力的计算................................................................................................103.3水力计算........................................................................................................133.4船舶泊稳条件................................................................................................18第四章闸室结构设计............................................................................244.1防渗墙与墙后排水........................................................................................244.2分离式闸室....................................................................................................244.2.1计算情况概述.......................................................................................244.2.2运用情况Ⅰ计算...................................................................................254.2.3运用情况Ⅱ计算...................................................................................324.3整体式闸室....................................................................................................374.3.1闸室结构尺寸确定...............................................................................374.3.2荷载计算...............................................................................................384.3.3稳定计算...............................................................................................414.3.4地基反力及底板内力计算...................................................................414.4工程量计算....................................................................................................454.5闸室结构选型................................................................................................454.6配筋计算.............................................................................
