毕业设计（论文） 论文题目 楼隘拦水堰施工图设计 Thesis Topic The constructional design of weir in Lou ai 楼隘拦水堰施工图设计 摘 要 在水利工程中，常根据不同的建筑条件及使用条件，将堰做成不同的类型。实用堰是水利工程中最常见的堰型之一。折线型实用堰作为低堰在中小型水利工程和农业水利工程中应用广泛47.80m，每侧23.90m；堰坝防洪标准采用10年一遇洪水，流量为9.03m3/s。 本次设计首先进行实地测量；再根据防洪标准、集雨面积等进行洪水设计；然后是堰坝设计，其中包括堰坝及其他建筑物尺寸确定、渗流计算、抗压抗滑计算、材料选择；接着施工组织设计，说明主体工程的施工要点；最后是投资概算与经济评价。在图纸上布置好各建筑物，并完成其相关配筋。 关键词：折线型实用堰，堰坝设计，施工图 The constructional design of weir in Lou ai Abstract For hydraulic engineering, weir often will be designed to many different types, under different terms and conditions of the use of building. Weir dam is one of the most common types in the water project. Line-type weir as a low weir is widely used in the small and medium hydraulic engineering and agricultural-water conservancy project. The Lou ai weir is designed to a line -type weir dam, the long of the proposed weir dam is full 10m, the elevation of weir crest is 10m, the elevation of upstream of river bed is 6.5m, and the downstream river bed is 4.3m (assuming height). The embankments of barrages will be constructed on both sides of length 47.80m, each side of 23.90m. The flood control standard of weir dam is in a 10-year frequency flood, flow rate is 9.03m3 / s. The first of design is measurement in field. Secondly, according to flood control standards, flood catchment’s area and so on to design. Thirdly, design the weir dam, including the size of weir dam and other buildings, seepage and sliding compression calculation, and material selection. Then design construction, descript the main engineering construction. Finally, investment budget and economic evaluation will be finished. It also needs good to arrange in the drawings of all buildings, and complete the related reinforcement.
