混凝土面板堆石坝设计

1毕业设计说明书题目：混凝土面板堆石坝设计专业：水利水电工程2混凝土面板堆石坝设计摘要混凝土面板堆石坝是用堆石或砂砾石分层碾压填筑成坝体，迎水面用混凝土面板作防渗体的坝，它对地形和地质条件都有较强的适应能力，并且施工方便、投资省、工期短、运行安全、抗震性好，因而其作为坝型选择具有很大的优势。通过地质地形，库区经济，料场位置及材料的分析，最终确定大坝为混凝土面板堆石坝。混凝土面板堆石坝作为一种特殊的土石坝，主要由堆石体和防渗系统组成，即：面板、趾板、垫层、过渡层、主堆石区和次堆石区。本文扼要介绍设计中进行的主要工作和设计成果：调洪演算、枢纽布置、坝体分区及坝料设计、坝体渗流及稳定分析、坝体沉降计算、坝体的细部构造以及地基处理、泄洪隧洞的设计等。关键词：混凝土面板堆石坝调洪演算枢纽布置坝体设计渗流计算稳定验算沉降计算泄水建筑物隧洞3ABSTRACTWithconcretepanelsasimperviousbodyontheupstreamside,concretefacerockfilldamislayeredwithrubbleorgravelandcompactedintorockfilldam.Becauseofitsstrongabilitytoadapttotheterrainandgeologicalconditions,convenientconstruction,lessinvestment,shortconstructionperiod,operationsafetyandgoodearthquakeresistance,concretefacerockfilldamhasagreatadvantagetobeasaselectionofdamtype.Concretefacerockfilldamasaspecialkindofearth-rockdam,ismainlycomposedofrockfillandimpervioussystem,namely:panel,toeboard,cushionlayer,transitionlayer,mainrockfillzoneandsecondaryrockfillzone.Thispaperbrieflyintroducedthemaindesignandthedesignresults:floodregulatingcalculation,layout,damzoninganddamdesign,damseepageandstabilityanalysis,settlementcalculation,thedamstructureandfoundationtreatment,releasefloodwaterstunneldesignetc.Keywords:concretefacerockfilldam,floodrouting,layout,designofdambody,seepagecalculation,stabilitycalculation,settlementcalculation,sluicestructure,tunnel4目录1..............................................................................................前言...................................................................................................62.基本资料和要求...........................................................................82.1大龙河水电站基本工程资料............................................................82.2设计工作要求.................................................................................153.洪水调节计算.............................................................................183.1调洪演算.........................................................................................183.2方案选择.........................................................................................514.坝址选择及枢纽布置.................................................................524.1坝址及坝型选择.............................................................................524.2枢纽总体布置.................................................................................535．大坝设计....................................................................................545.1土石坝坝型选择.............................................................................545.2大坝轮廓尺寸的拟定.....................................................................555.2.1坝体剖面设计............................................................................................555.2.2坝体材料分区及坝料设计.......................................................................635.2.3面板、趾板、连接板及分缝止水设计...................................................666．坝体计算....................................................................................7156.1渗流分析..........................................................................................716.2稳定分析.........................................................................................796.3坝体沉降计算.................................................................................937.基础处理及细部构造.................................................................947.1基础处理.........................................................................................947.2细部构造设计.................................................................................958.隧洞设计.....................................................................................978.1泄水方案的选择.............................................................................978.2隧洞选线与布置..............................................................................998.3隧洞的体形设计...........................................................................1008.3.1进口建筑物..............................................................................................1008.3.2洞身断面型式和尺寸..............................................................................1018.3.3出口消能段..............................................................................................1028.3.4隧洞的水力计算......................................................................................1028.3.5出口消能验算..........................................................................................1078.3.6隧洞的细部结构.......................................................................................111结语................................................................................................115专题：混凝土面板堆石坝的渗流控制.......................................115外文文献及翻译............................................................................122参考文献........................................................................................1386谢辞..........................................................................................1391.前言毕业设计是大学学习的重要环节，对培养工程技术人员独立承担专业工程技术任务重要。通过毕业设计可以进一步培养和训练我们分析和解工程实际问题及科学研究的能力。
