**市**河河道整治工程设计矩形断面方案摘要**河穿越**市，本次整治段从黄河路—湨河入口段全长度为1950米，为了保护河道两岸人民群众的生命财产安全，所以进行本次河道整治工程，此次本次设计的主要内容是：选定设计方案，设计河道横断面，推求水面线，进行河道堤防设计，河道中心线设计，河道护坡工程设计和栏杆、排水沟、伸缩缝等细部结构设计，以及施工组织设计工程量统计与工程概算。本次设计的方法及过程有以下：选择断面形式，矩形断面水力试算，通过伯努利方程推求水面线高程，然后设计堤顶高度；为了规顺洪水河槽稳定堤岸，进行河道中心线设计，首先在平面图上粗拟中心线，然后对有折角的位置圆弧化修改，圆弧半径应取3—5倍的水面宽度；最主要的设计是护坡工程设计，由于断面采用矩形断面，故只进行挡土墙设计和校核，细部结构设计包括的主要内容有栏杆设计、排水沟设计、伸缩缝设计，最后是施工组织设计工程量统计与工程概算。大大提高了该河段泄洪能力，减轻沿河两岸地区的防汛压力，河道将按50年一遇洪峰流量设计，100年一遇校核洪水不漫堤，防洪效益十分显著，配合挡土墙护坡以及堤顶道路绿化带，可增加植被，美化环境，减少大气污染，有效防止水土流失，避免附近沟道淤塞，保护当地生态环境，增强河道沿岸绿化，改善了当地人民的生产、生活条件。关键词：河道中心线布置；矩形断面；施工组织设计；JiyuanSangYurivercoursetheengineeringdesign-rectangular华北水利水电学院2010届本科毕业设计cross-sectionschemeAbstractSangYuriver,thisregulationperiodthroughjiyuanJuriverentrancefromdimness-allfor1950meterslengthofsection,inordertoprotecttherivertothelivesandpropertyofthepeopleonbothsidesofmasses,sosafeforthisriverregulationengineering,themaincontentsofthisdesignis:selecteddesignscheme,designriverchanneltransversesection,thewaterline,deriveriverleveecenterlinedesign,design,riverchannelrevetmentengineeringdesignandbaluster,drains,expansionjoints,suchasthestructuredesignanddetailstheconstructionorganizationdesignquantitystatisticsandprojectbudget.Thedesignmethodsandprocesseshavethefollowing:selectsectionform,rectangularcross-sectionhydraulictrytocalculate,throughtheBernoulliequationdeducedthewaterline,thendesignelevationconstructedheight;Inordertogaugetheriverbank,stablefloodcenterlinedesign,firstinrivertoplan,andthenthecenterlineofcoarsepositionofadiscountAngleofcirculararcmodifications,arcradiusshouldbetake3-5timesthesurfacewidth;Themaindesignisrevetmentengineeringdesign,because,itadoptsrectanglesectionsectiononlyretainingwalldesignandcheck,detailsthemaincontentofthestructuredesign,includingarailingdesign,drainagedesign,design,finalisadjustableseamtheconstructionorganizationdesignquantitystatisticsandprojectbudget.Afterthecompletionoftheprojectwillgreatlyimprovethebehaviors,reducethedischargecapacityalongtheriver,theriverfloodareawillpresspressurein50yearsthepeakflowdesign,100yearsinacheck华北水利水电学院2010届本科毕业设计dam,aimlessandfloodwatersareremarkable,cooperatefloodcontrolbenefitprotectionandretainingwallsconstructedroadgreening,canincreasevegetation,beautifytheenvironment,reducingairpollution,effectivelypreventsoilerosiongully,avoidsiltationneartoprotectthelocalecologicalenvironmentandenhancingthechannelcoastgreeningandimprovethelocalpeople'sproductionandlivingconditions.Keywords:centerlinedesign，sqarecross-section，constructionorganization华北水利水电学院2010届本科毕业设计目录摘要.......................................................................................................................................................IAbstract.............................................................................................................................................II1项目基本资料说明..........................................................................................................................11.1概况.......................................................................................................................................11.2工程任务...............................................................................................................................11.3工程设计依据.......................................................................................................................11.4工程地质...............................................................................................................................21.4.1地形地貌....................................................................................................................21.4.2地基土层....................................................................................................................21.4.3地下水........................................................................................................................21.4.4不良地质作用与不良地质现象................................................................................21.5气象及水文资料...................................................................................................................22整治方案..........................................................................................................................................42.1项目区现状...........................................................................................................................42.2整治目标...............................................................................................................................42.3整治设计方案选定...............................................................................................................43河道整治工程设计..........................................................................................................................63.1工程等别及建筑物级别.......................................................................................................63.2设计基本资料................................................................................
