摘 要 本水利枢纽工程同时具有防洪、发电、灌溉、渔业等综合作用。该枢纽由挡水建筑物、泄水建筑物和水电站建筑物等组成，各部分组成建筑物方案与布置分述如下：挡水建筑物为粘土斜心墙土石坝，按直线布置在河弯地段；坝体防渗体为粘土斜心墙，斜心墙上下游均设反滤层；坝基防渗体河床中央地段和左岸为混凝土防渗墙，右岸为粘土截水墙；坝体排水河床段采用棱体排水，下游水位以上采用贴坡排水，排水体与坝体、坝基之间设置反滤层；上游护坡采用干砌石护坡，下游采用碎石护坡；坝顶上游设置防浪墙，下游设置栏杆以策安全。泄水建筑物采用隧洞泄洪方案。泄洪隧洞采用“龙抬头”无压泄洪的型式，并与施工导流隧洞、放空洞相结合。通过隧洞水面线计算最终确定洞身尺寸。最后对隧洞细部及放空洞进行设计。本设计严格按照国家规范进行了以上各建筑物的设计。土石坝设计是坝工毕业设计的重要内容之一。本设计共历时9周完成。本坝工设计在王玲玲老师的指导和帮助下完成，在此致以诚挚的谢意。对于本设计中的不妥及错误之处，恳请老师批评指正。ABSTRACTThis hydropower project is mainly concerning on the flood control, hydroelectric generation, irrigation & fisheries.The project is consisting of water retaining structure, sluice structure and power house and their layout are as below:Earthrocked dam with inclined central core is chosen as water retaining structure, which is placed on the binding portion of the river .Clay inclined control core is not as a seepage control structure in dam. On the upstream & downstream of this seepage control structure a layer of filter is placed. On the river bed portion & left bank portion of dam foundation, concrete call off wall is used where on the right bank, clay soil is used. For the drainage purpose of dam, prism drainage is used on the river bed portion & a bore downstream water level drain on embankment slope is used. In between drainage structure & dam a layer of filter is set. Drylaid stone masonry is used on upstream, slope & crushed stone slope is used on downstream slope. On the tip of dam ,wave protection wall is place on upstream & bar is place on the downstream.Flood discharging tunnel is used on a sluice structure. The funnel is combined with diversion tunnel & is placed on the right bank.In this design, National Standards are strictly considered for the designing of each structure.目 录摘 要2ABSTRACT3第一章 概述41.1 毕业设计主要目的和作用41.2 设计内容和基本方法41.3 具体成果5第二章 工程概况52.1 流域概况52.2 气候特性62.3 水文特性72.4 工程地质82.5 建筑材料112.6 经济资料11第三章 洪水调节计算143.1 洪水调节计算143.2 堰顶高程及泄洪孔口的选择153.3 调洪演算结果与方案选择16第四章 坝型选择及枢纽布置174.1坝址及坝型选择174.2枢纽组成建筑物184.3 枢纽总体布置20第五章 土石坝设计225.1 坝型选择225.2 大坝轮廓尺寸的拟定235.3 土料设计265.4 渗流计算365.5 稳定分析计算395.6 大坝基础处理415.
