4、据；2、掌握列表试算法和半图解法的基本原理、方法、步骤及各自的特点；3、了解工程设计所需洪水调节计算要解决的课题；4、培养学生分析问题、解决问题的能力。二、设计基本资料2.1设计基本资料XX水电站水库正常蓄水位355.00m，总库容23.38亿m3，具有完全年调节性能。属一等大(1)型工程，工程枢纽由混凝土面板堆石坝、右岸溢洪道、左岸引水隧洞、坝后地面厂房等组成，其中大坝、溢洪道、引水隧洞进水口为1级水工建筑物，正常运用洪水重现期为1000年，非常运用洪水重现期为10000年。XX水电站承担下游防洪任务，为使下游城市及农田不受淹没，同时减少上游水位雍高带来的经济损失。具体防洪要求如

5、下：防洪限制水位为340.00m，遭遇设计洪水位时，最高库水位不得超过357.0m，允许下泄流量为12500m3/s；遭遇校核洪水位时，最高库水位不得超过360.0m，允许下泄流量为15300m3/s。XX水电站采用溢洪道泄流，溢洪道设有闸门，溢洪道溢流孔数为3孔，单孔宽度为20.7m，溢洪道溢流孔高18.0m，闸顶高程362.0m，进水渠底板高程330.0m，为WES型低实用堰，堰顶高程337.0m。泄槽宽度69.0m，纵坡i=0.15，设1.0m厚分离式钢筋混凝土底板。末端接挑流鼻坎，鼻坎高程为282.014m，挑射角为25°，反弧半径50.0m，闸墩墩头以下溢洪道总长385.
