摘要
适当修建大坝可以实现一个流域地区发电、防洪、灌溉的综合效益E江位于我国西南部地区，通过对其地形地质、水文资料、气候特征的分析，结合当地的建筑材料，设计适合的枢纽工程来帮助流域地区实现很好的经济效益。根据防洪要求，对水库进行洪水调节计算，确定坝顶高程及泄洪建筑物尺寸；通过分析，对可能的方案进行比较，确定枢纽组成建筑物的形式、轮廓尺寸及水利枢纽布置方案；详细作出大坝设计，通过比较，确定坝的基本剖面与轮廓尺寸，拟定地基处理方案与坝身构造，进行水力、静力计算；对泄水建筑物进行设计，选择建筑物的形式、轮廓尺寸，确定布置方案，拟定细部构造，进行水力、静力计算。水库建成后，可建装机容量约为24MW的水电站，多年平均发电量可达1.05亿度；可增加灌溉面积约10万亩；水库配合下游河道整治等措施，可以很大程度的减轻洪水对下游城镇、厂矿、农村、公路、铁路以及旅游景点的威胁；可为发展养殖创造有利条件。

Summary
Proper construction of the dam can implement a comprehensive benefits of watershed areas of power generation, flood control, irrigation e River is located in southwestern region of China, by its topographic analysis of geological, hydrological data, climate, local building materials, designed to fit the project to help watershed areas to achieve good economic efficiency. According to flood control requirements, on reservoir for flood regulation calculation, determines dam top elevation and the flood buildings size; through analysis, on May of programme for comparison, determines hub composition buildings of forms, and outlines size and the project layout programme; detailed made dam design, through comparison, determines dam of basic profile and outlines size, developed Foundation processing programme and dam body constructed, for hydraulic, and static force calculation; on discharge buildings for design, select buildings of forms, and outlines size, determines layout programme, Elaboration of detail structure, hydraulic, static calculations.
After being completed, is able to build capacity around the 24MW hydropower station, multi-annual average generating capacity of up to 105 million; to increase the irrigation area is about 100,000 acres; lower reservoirs combined with measures such as treatment, can greatly alleviate flooding downstream towns, factories, rural areas, highways, railways and tourist attractions of the threat can create favourable conditions for the development of aquaculture.
Key words: dam dam design for project layout of type selection for Foundation treatment
