山东科技大学毕业设计(论文) 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。 通过对扬州地形地质、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。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。 【关键词】：坝工设计；渗流分析；稳定分析；溢洪道设计；基础处 理。 山东科技大学毕业设计(论文) Abstract Appropriate construction of dam can be achieved in a basin area of power generation, flood control, irrigation benefit. D river is located in our country southwest, through to its geological, hydrological data, climate analysis, combined with the local building materials, design suitable for the projec to help the region to achieve good economic benefit. According to the requiremen of flood control, flood regulation computation of reservoir, to determine the crest elevation and release flood waters building size; through the analysis, on the possible options, determine the hub of the building form, dimensions and water conservancy hub layout plan made in detail; dam design, through the comparison, determining basic profiles and dimensions, make the foundation treatmen scheme and the dam body structure, hydraulic, static calculation of outle structures; design, choice of building form, outline dimensions, to determine the layou scheme, make detail structure, hydraulic, static calculation. Reservoir with river regulation measures, can greatly reduce the flood on the downstream towns, factories and mines, rural, highway, railway and the tourist a ractions of the threat; create favorable conditions for development of aquaculture.
