扬州大学本科生毕业设计 PAGE  PAGE 137 摘 要 本闸位于江苏省高邮市某中型灌区干渠渠首，为渠首取水水工建筑物。建筑物等级为一级。计算得本工程设3孔，每孔净宽5.0m，闸底板长17m，闸底板厚1.0程采用平面钢闸门，采用QPQ-12.5的单吊点卷扬式启闭机。经计算设计消力池长为15m，深1.0，消力池底板厚为0.5m，海漫长为20m。上下游翼墙结构形式采用钢筋混凝土扶壁式挡土墙。 本工程中防渗计算采用改进阻力系数法，底板内力按弹性地基梁法计算。本工程设计主要由水力设计、消能防冲设计、闸基渗流计算、闸室结构布置、闸室稳定计算、闸室结构计算、两岸连接建筑物布置、两岸连接建筑物结构计算等几个部分组成。 关键词：水力计算 稳定计算 结构计算 边荷载 弹性地基梁 Abstract This floodgate located at Jiangsu Province Gaoyou some medium irrigation area main channel canal head, takes the water hydraulic engineering structure for the canal head. The building rank is first-level. Calculates this project to suppose 3, each extends 5.0m only, floodgate ledger wall long 17m, floor or bottom of sluice gate thickness of slab 1.0m. This project uses the plane steel strobe, uses QPQ-12.5 Shan Disodium to hoist the type gate. After the computation design toe basin length is 15m, deep is 1m, the toe basin bottom thickness of slab is 0.5m, and the sea long is 21m. The upstream and downstream wing wall structural style uses the reinforced concrete buttress type bulkhead. In this project the anti-seepage computation uses the improvement resistance method of correlates, the ledger wall androgenic force according to elastically the foundation beam law computation. the this engineering design mainly by the water power design, disappears can against flush the design, the floodgate base transfusion computation, the brake chamber structural arrangement, the brake chamber stable computation, the brake chamber structure computation, both banks connection building arrangement, both banks connection building structure computation and so on several parts to be composed. Key word: Water power computation stable computation structure computation load elastically foundation beam毕业设计（论文）原创性声明和使用授权说明 原创性声明 本人郑重承诺：所呈交的毕业设计（论文），是我个人在指导教师的指导下进行的研究工作及取得的成果。尽我所知，除文中特别加以标注和致谢的地方外，不包含其他人或组织已经发表或公布过的研究成果，也不包含我为获得 及其它教育机构的学位或学历而使用过的材料。对本研究提供过帮助和做出过贡献的个人或集体，均已在文中作了明确的说明并表示了谢意。 作 者 签 名：　　 　 　　日　 期：
