毕业设计（论文）说明书题目：TJ土石坝除险加固设计系名建筑工程系专业水利水电学号6008207251学生姓名高明晶指导教师王海军年月日摘要我国是拥有水库最多的国家，水库对国民生产生活用水具有重要的意义。土石坝是我国水利工程中各种坝型应用最多的一种，但由于其建设时期的历史特殊性，多数土石坝存在着不同程度的设计缺陷或质量问题。该文主要进行了下列工作:回顾总结了我国土石坝发展的基本概况及运行现状，对土石坝病害的种类及评判方法进行归纳;综述了土石坝加固技术及方法，对各种除险加固措施进行了分析比较，并对TJ水库除险加固进行了系统的分析，结合坝体蓄水后不同水位条件下坝体浸润线的变化，分析模拟水位的变化对坝体稳定性和变形等方面的影响。从大坝病害勘察、分析，到除险加固设计直至工程施工处理均进行了较为全面的讨论。关键词：土石坝；除险加固；渗流分析；稳定分析AbstractOurcountryisoneofthenationsowningthelargestquantityofreservoirsintheworld,andthereservoirplaysagreatroleinthelifeandproductionofourpeople.Theearth-rockdamisthemostfrequently-useddaminhydraulicengineeringinourcountry.Asaresultofthelarge-scaleconstruction，mostoftheearth-rockdamsexistdesignorqualityproblemsindifferentdegree.Inthepaperthefollowingworkismainlycarried.Itreviewsandsummarizesthedevelopmentandoperationofarth-rockdamsinChina,inducesthevariousdiseaseofearth-rockdamsanditsmeasureofjudgement;Thecommonlyusedtechnicalmethodofreinforcementinearth-rockdam’sstrengthenissummarizedtobeanalyzedandcompared.Combiningthedifferentwaterlevelinthedamafterused，primarilyanalyzetheinfluenceonthestressinthedamproducedbythechangingofwaterlevel.ThepaperhasdonesomeresearchsystematicallyontheprocedureofdoingawaywiththedangerousconditionsoftheTJReservoiranditsreinforcementaswellasthesurveyandanalysisofthediseaseddam,thereinforcementdesign,andthetreatingofconstruction.Keywords:earth-rockdam;reinforcementofdangerousdam;seepageanalysis;stabilityanalysis目录第一章绪论...........................................11.1引言...............................................11.2国内外发展现状.....................................11.3研究目标...........................................2第二章土石坝的病害及处理技术........................12.1土石坝的病险及特征.................................12.2土石坝病害的主要原因...............................32.3加固方法分类及选用原则.............................32.3.1方法选用原则...................................32.3.2加固方法分类及适用范围.........................42.4加固新技术应用.....................................5第三章TJ水库工程概况................................73.1基本情况...........................................73.2水文..............................................73.2.1流域概况......................................73.2.2设计洪水......................................83.3工程地质与工程质量................................103.3.1区域地质概况.................................103.3.2溢洪道工程地质...............................113.4工程除险加固的必要性.............................113.5工程规模和任务....................................123.5.1工程等级及建筑物级别.........................123.5.2设计洪水标准.................................123.5.3洪水调节.....................................123.5.4工程除险加固的任务...........................123.6基本资料..........................................13第四章TJ水库除险加固复核..........................144.1坝顶高程复核......................................144.1.1基本资料........................
