1、大型水闸设计毕业论文大型水闸设计摘要本毕业设计的题目是大型水闸设计，本工程位于河南省某县城郊处，该河属稳定性河流，河面宽约200m,深约7〜10mQ拦河闸所担负的任务是：正常情况下拦河截水，抬高水位，以利灌溉，洪水时开闸泄水，以保安全。本工程建成后，可利用河道一次蓄水800m3，调蓄水至两岸沟塘，大量补给地下水，有利于进灌和人畜用水，初步解决40万亩农出的灌溉问题并为工业生产提供足够的水源，同时对漁业、航运业的发展,以及改善环境，美化城乡都是极为有利的。本设计的内容包括水闸等级划分、闸址选择、总体布置、闸型确定、拟定闸孔尺寸及闸墩

2、厚度、防渗排水设计、闸墩、闸底板设计、闸室的稳定计算。其屮通过设计流量与校核流量确定闸孔总净宽，再根据《闸门设计规范》选定单孔净宽。根据闸基地质条件决定出闸底板形式以及闸墩厚度。由于本闸位于平原地区，河床的抗冲刷能力较低，所以采用底流式消能。闸门局部开启情况，作为消能防冲设计的控制情况。防渗设计屮采用改进阻力系数法进行渗流计算。闸室的稳定计算中考虑到了完建无水期和正常扌肖水期网种情况下的荷载组合进行验算。关键词：闸门、闸墩、消力池、渗流、地基承载力、稳定计算AbstractTheschooldesignonthetopicofma
