Abstract

The dam in Mianjiang reservoir is located in Jiangyou City, Sichuan Province. It is an irrigation, flood control, small fish and other integrated functions (2) reservoir. It has been built for many years, so there are many problems such as seepage dam, spillway erosion serious, drainage facilities aging. Focus on these issues, this design mainly to reservoir reinforcement, the main contents include the design flood review, peak discharge, recheck computation of spillway maximum discharge capacity, the analysis of dam seepage, the analysis of dam stability, the design of reinforcement and spillway strengthening, all of this based on the Mianjiang reservoir basis of basic data. In order to protect downstream residents, we have to do analysis of dam seepage, and complete the dam heightening project.

Key word : Dam; seepage; flood; spillway; reinforcement

大型水闸设计

摘要

本毕业设计的标题是大型水闸设计，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200 m，深约7~10 m。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，以保平安。 本工程建成后，可利用河道一次蓄水800万m3，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，初步处理40万亩农田的灌溉征询题并为工业消费提供足够的水源，同时对渔业、航运业的开展，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厚度、防渗排水设计、闸墩、闸底板设计、闸室的稳定计算。其中通过设计流量

《闸门设计标准》与校核流量确定闸孔总净宽，再按照选定单孔净宽。按照闸基地质条件

决定出闸底板方式以及闸墩厚度。由于本闸位于平原地区，河床的抗冲刷才能较低，因而采纳底流式消能。闸门部分开启情况，作为消能防冲设计的操纵情况。防渗设计中采纳改良阻力系数法进展渗流计算。闸室的稳定计算虑到了完建无水期和正常挡水期两种情况下的荷载组合进展验算。

关键词：闸门 、闸墩 、消力池 、 渗流 、地基承载力 、稳定计算

Abstract

The school design on the topic of major flood gate design. This project is located in Henan Province a county and city outskirts. The River is stability River. river width of about 200m, about 7 to 10m. The River Gate the tasks are: Under normal circumstances the river damming water to raise water for irrigation, flood, open the gate sluicing to ensure safety. This project is completed, and you can use river a water 8 million m 3, to water and the two sides of Tong, a large supply underground water, and conducive to irrigation and irrigation water, has initially solved 400,000 mu of farmland irrigation and industrial production to provide sufficient water for fishing, shipping industry, and improve the environment and beautify urban and rural areas are extremely beneficial.

The design of the sluice gates hierarchy, site selection, overall arrangements, gates, established in gate Hole size and design gate Tun thickness, impermeable drainage design, Gates Tun, Gates plate design, lock the stable basis. The adoption of the design of the flow of traffic nuclear school gates hole the total net width, selected in accordance with single hole net wide. In accordance with the base gate conditions on board the gates and gate Tun thickness. The gate is located in the plains, River Plate of resistance against soil erosion is comparatively low, so the bottom streaming consumer. Gates partially open, as a consumer can prevent Chong design of the situation under control. impermeable design of the adoption of improved resistance coefficient of seepage. lock the stable basis, taking into account the end up without water and normal and water for two of the load combination residue.

Keywords ：Gates, Gates Tun， stilling basin， transfusion， Foundation capacity， stable basis
