斜心墙土石坝初步设计-大学论文.doc

5657中文摘要某江河位居于我国西南地区，在该江中上游建造以斜心墙土石坝为挡水建筑物的水利枢纽。水利枢纽以防洪为主要任务，以发电、灌溉等为该地区创造经济价值。本毕业设计侧重于拦河坝段斜心墙土石坝的挡水建筑的初步设计。首先，应用该枢纽的各项具体数据，来确定出工程等级和建筑物的等别。调洪方案初步拟定后，应用列表计算来确定出设计洪水位、校核洪水位、设计泄洪量、校核泄洪量。随后针对土石坝各种坝型方案进行定性分析比对，最终选择斜心墙土石坝。初步拟定出斜心墙土石坝的剖面尺寸后，取其三个特征剖面进行渗流计算，校核渗透逸流处的渗透坡降是否满足要求。本毕业设计采用折线法的VB编程进行斜心墙土石坝的稳定分析。最后，对坝体的细部构造进行设计。本设计以《碾压式土石坝设计规范DL/T5395-2007》为基本设计依据。此外参考了与土石坝的有关资料和书籍。由于知识有限，对于本设计中的不妥及错误之处，恳请批阅批评指正。关键词：斜心墙土石坝渗流计算稳定分析毕业设计AbstractAriverinsouthwestChinaranked,builtobliquecoreembankmentofretainingwatercontrolstructuresintheupperreachesoftheriver.WaterControlfloodcontrolasitsmaintasktogenerateelectricityandirrigationintheregiontocreateeconomicvalue.Thegraduationprojectfocusedonthepreliminarydesignoftherampcoreembankmentdamsectionofretainingthebuilding.First,theapplicationofthespecificdataofthehub,todeterminethelevelofengineeringandbuildings,etc.donot.Afterthefloodprogramtentatively,theapplicationlistcalculationstodeterminethedesignfloodlevel,checkfloodlevel,thedesigndischargevolume,checkingflooddischarge.Followedbyaqualitativeanalysisofthevariousdamembankmentdamtypeschemecomparison,thefinalchoiceobliquecoreembankment.Aftertheinitialdevelopmentofthecross-sectionalsizeoftheobliquecoreembankment,whicheverofthethreecharacteristicprofilesinseepagecalculation,osmoticgradientatcheckpermeateslipmeetstherequirements.ThegraduationprojectusingVBprogrammingdoglegmethodofstabilizationanalysisofobliquecoreembankment.Finally,thedetailedstructureofthedamdesign.Thedesign"rollercompactedembankmentdamdesignspecificationsDL/T5395-2007"asthebasicdesignbasis.Furtherreferencetorelevantinformationandembankmentdamsandbooks.Duetolimitedknowledge,forthisdesigniswrongandwrong,urgemarkingcriticism.Keywords:InclinedCoredamseepagecalculationstabilityanalysisgraduation目录绪论1第一章工程概况21.1工程流域概况21.2当地气候特征21.3洪峰流量资料21.4坝址地质资料21.5地震资料31.6建筑材料31.7交通状况31.8枢纽特征31.8.1水库情况31.8.2发电31.8.3防洪31.8.4灌溉3第二章坝型选择及枢纽布置概述62.1坝型的选择62.2枢纽的总体布置72.2.1挡水建筑物72.2.2泄水建筑物72.2.3水电站建筑物7第三章洪水调节计算83.1工程等别及建筑物等级的判定83.2洪水标准的确定83.3泄洪方式的确定83.4
