大学学士学位论文I摘要本文为面混凝土面板堆石坝设计说明书，根据所给基本资料及面板堆石坝的特点进行调洪演算，本设计中一共选取了四种方案，经过调洪演算并结合下游防洪要求及经济因素等的考虑，最终选择方案四，即选择堰宽为75m的方案。本设计主要进行了调洪演算、坝体分区设计、溢洪道设计、溢洪道水面线计算、坝体渗流分析及坝体稳定计算等几个方面。本设计中河岸溢洪道布置在河流右岸，为正槽溢洪道。大坝高71.3m，上游坝坡坡度为1.4，下游坡度为1.3坝轴线长度为449.4m，布置在河流转弯处。经坝体稳定分析和渗流计算，本方案满足要求。关键词：混凝土面板堆石坝调洪演算坝体设计渗流计算稳定验算河岸溢洪道大学学士学位论文IIABSTRACTThispaperforthesurfaceofconcretefacerockfilldamdesignspecifications,accordingtothebasicinformationandgiventhecharacteristicsofconcretefacerockfilldamforfloodregulatingcalculation,thetotalselectioninthedesignofthefourkindsofsolutions,throughthecombinedwiththedownstreamfloodcontrolrequirementsforfloodregulatingcalculation,andeconomicfactors,finallyfouroptions,whichchoosestheplanofdamis75mwide.Thisdesignmainlyforfloodregulatingcalculation,design,designofspillway,thesurfacespillwaydampartitionline,damseepageanalysisanddambodystabilitycalculation.ThedesignandarrangementofthespillwayintheBanksoftheriverontherightbankoftheriver,spillwaywasrightinthegroove.71.3mhighdam,theupstreamdamslopedegreeis1.4,thedownstreamslope1.3damaxislengthof449.4m,decorateinthebend.Thisschemebythedamseepagecalculation,stabilityanalysisandmeettherequirements.Keywords:concretefacerockfilldam,floodrouting,designofdambody,seepagecalculation,Stabilitycalculation,Thebankspillway大学学士学位论文目录摘要......................................................................................................................IABSTRACT......................................................................................................II第1章工程基本资料..................................................................................11.1流域概况及枢纽任务..........................................................................11.2设计要求..............................................................................................21.3枢纽设计基本资料..............................................................................2第2章调洪计算............................................................................................92.1调洪演算.................................................................................................92.2方案选取...............................................................................................15第3章坝址选择及枢纽布置..................................................................173.1坝址及坝型选择..................................................................................173.2枢纽总体布置......................................................................................183.3土石坝坝型选择...................................................................................183.4大坝轮廓拟定.......................................................................................193.5混凝土面板、趾板设计.......................................................................253.6分缝止水设计.......................................................................................27第4章坝体计算..........................................................................................294.1渗流分析...............................................................................................294.2坝体稳定分析.......................................................................................36大学学士学位论文4.3坝体沉降计算.......................................................................................46第5章坝基处理..........................................................................................495.1基础处理...............................................................................................495.2细部构造设计......................................................................................50第6章溢洪道设计.....................................................................................536.1泄水方案选择.......................................................................................536.2溢洪道选线...........................................................................................536.3溢洪道设计...........................................................................................536.4溢洪道水力计算...................................................................................56结语.................................................................................................................65专题：河岸溢洪道的适用条件................................................................67外文文献及翻译............................................................................................71FuzzyEarthworkDynamicAllocationandOptimizationforConstructionofHighConcreteFaceRockfillDam..........................................................71高混凝土面板堆石坝施工过程中土石方分配的模糊优化.....................75参考文献..........................................................................................................79谢辞.................................................................................................................80大学学士学位论文1第1章工程基本资料1.1流域概况及枢纽任务1.1.1流域概况虞江位于我国西南地区，流向自东向西北，全长约122公里，流域面积2558平方公里，在坝址以上流域面积为780平方公里。本流域大部分为山岭地带，山脉、盆地相互交错于其间，地形变化剧烈，流域内支流很多，但多为小的山区河流，地表大部分为松软沙岩、页岩、玄武岩及石灰岩的风化层，汛期河流含沙量较大，冲积层较厚，两岸有崩塌现象。本流域内因山脉连绵，交通不便，故居民较少，全区农田面积仅占总面积的20%，林木面积约
