南沟门坝水利枢纽工程布及泄水建筑物设计.doc

西安理工大学毕业设计（论文） 题 目 南沟门常态混凝土重力坝 及溢流坝段设计设计 专 业 水利水电工程 班 级 工115班 学 生 张先帅 指导教师 李守义 2015 南沟门常态混凝土重力坝及溢流坝段设计 摘 要 南沟门水利枢纽工程位于陕西省延安市黄陵县境内，水库坝址位于葫芦河河口上游3公里处的南沟门附近，距黄陵城约25公里，距洛川县城约17公里，距延安市约120公里，距西安市约180 公里。该水利枢纽工程主要任务是向延安石油化学工业基地及当地城乡生活供水，改善其灌溉条件，并利用供水进行发电。本次毕业设计分析了坝址的地形和地质条件，对比几种坝型最终选取常态混凝土重力坝和坝轴线并进行了枢纽布置。枢纽建筑物包括泄水建筑物、挡水大坝、底孔、供水管道和电站等。然后对该工程的溢流坝及底孔的形式和消能及防冲进行了设计。坝体剖面的稳定和应力计算，荷载组合取了基本组合和特殊组合两种不同的情况，以正常蓄水位时的荷载组合作为基本组合；以校核荷载和地震荷载作为特殊组合。设计中选取了坝基面和廊道底部截面作为计算截面，对坝体的两种稳定和强度都进行了计算，结果都满足要求。本次设计的主要成果有：设计说明书1份，设计图纸6张以及其他相关附图附表等。 关键词： 常态混凝土重力坝；溢流坝；底孔；设计 。 Copper cash dam water conservancy hub project layout andWater discharge building design ABSTRACT Copper cash dam located in hanjiang river dam site tributary jade belt linked to the downstream, the reservoir for a factory in industrial water is given priority to, and compensation of farmland irrigation water downstream, and flood control, power generation, fish, and other comprehensive use of water conservancy hub project. The graduation design analysis of the dam site topographical and geological conditions, compared several dam type selection ultimately normal concrete gravity dam and dam axis and the general layout.Hub buildings including outlet structure,Block water dam,underport,Water supply pipe and power stations.Then the spillway and bottom outlet in the form of engineering and the energy dissipationand scour protection design. The stability of the dam profile and stress calculation, the load combination to take thebasic combinations and special combination of two different situation, normal water level of theload combination as the basic combination; checking loads and seismic loads as special combinations.In the design of the dam foundation and corridor on the surface as the section at the bottom section on the dam two stability and strength are calculated, the result is meet the r
