文档介绍：摘 要
土石坝泛指由当地土料、石料或混合料，经过抛填、辗压等方法堆筑成挡水坝。当坝体材料以土和砂砾为主时，称土坝、以石渣、卵石、爆破石料为主时，称堆石坝；当两类当地材料均占相当百分比时，称土石混合坝。土石坝是历史最为悠久一个坝型。近代土石坝筑坝技术自２０世纪５０年以后得到发展，并促成了一批高坝建设。现在，土石坝是世界坝工建设中应用最为广泛和发展最快一个坝型。
因农业生产需要，云南大姚县拟在县城东北7km金碧镇施永屯办事处龙林村兴建一个土石坝型浇灌水库。在对本处自然地理和水文特征、工程地质情况及周围建筑材料了解以后。经过具体分析以后，选择了坝轴线并进行了枢纽部署。依据毕业设计要求利用内插法进行了调洪演算，得到了设计洪水位和校核洪水位。进行了枢纽部署，划分了工程等级和关键建筑物等级。深入进行了坝体剖面设计，计算出了坝顶高程。然后又进行了渗流计算、稳定计算、细部结构设计、坝身结构设计、输水建筑物设计和溢洪道部署等十章内容。具体见设计书。
关键词：土石坝；调洪演算；输水建筑物。
Abstract
Earth dam refers to local soil material, stone or mixture, after throwing filling, rolling and other methods piled into the dam material to the soil and gravel-based, said the dam, when gravel, pebbles, stone blasting mainly known rockfill dam; When two categories account for a considerable proportion of local materials, the known debris mixed dam is one of the oldest type of dam. Modern technology has been developed dam embankment dam since the 20th century, 50 years later, and contributed to a number of dam building. Currently, the construction of earth dam dam is the world's most widely used and one of the fastest growing type of dam.
Because of the need for agricultural production, Yunnan Dayao County proposes to construct an earth dam irrigation reservoir in the northeast of the county town Splendor Long Lam, Tuen 7km of office. After the natural geographical and hydrological characteristics of the department, engineering geology and understanding of the surrounding building materials. After a detailed analysis of the dam axis and select the project layout. Graduation requirements based on the use of interpolation method of flood routing, got the design flood level and check flood level. Conducted a project layout, dividing the project level and the level of the main building. Conducted a thorough cross-section of dam design, calculate the crest elevation. And then conducted a seepage calculation, stability calculation, detail design, structural design of the dam body, water
