土石坝除险加固

毕业(Ye)设计〔论(Lun)文〕说(Shuo)明书题(Ti)目：TJ 土石坝除险(Xian)加固设计系 名 建筑工程系专 业 水利水电 学号 6008207251 学生姓名 高超晶 指导老师 王海军 年 月 日摘(Zhai)要(Yao)我国是拥有水库(Ku)最多的国家，水库对国民出发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(Dan)由于其建设时期的历史特别性，多(Duo)数土石坝存在着不同程度的设计缺陷或质量问题。该文主要进行了以下工作:回忆总结了我国土石坝开展的底子概况及运行现状，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，对各种除险加固办法进行了阐发比拟，并对 TJ 水库除险加固进行了系统的阐发，结合坝体蓄水后不同水位条件下坝体浸润线的变化，阐发模拟水位的变化对坝体不变性和变形等方面的影响。从大坝病害勘察、阐发，到除险加固设计直至工程施工处置均进行了较为全面的讨论。关键词：土石坝；除险加固；渗流阐发；不变阐发AbstractOur country is one of the nations owning the largest quantity of reservoirs in the world, and the reservoir plays a great role in the life and production of our people. The earth-rock dam is the most frequently-used dam in hydraulic engineering in our country.As a result of the large-scale construction，most of the earth- rock dams exist design or quality problems in different degree. In the paper the following work is mainly carried.It reviews and summarizes the development and operation of arth-rock dams in China,induces the various disease of earth-rock dams and its measure of judgement;The commonly used technical method of reinforcement in earth-rock dam’s strengthen is summarized to be analyzed and compared.Combining the different water level in the dam after used，primarily analyze the influenceonthestressinthedamproducedbythe changingofwaterlevel.The paper has done some research systematically on the procedure of doing away with the dangerous conditions of the TJ Reservoir and its reinforcement as well...
