1、摘要土石坝泛指由当地土料、石料或混合料，经过抛填、辗压等方法堆筑成的挡水坝。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比例时，称土石混合坝。土石坝是历史最为悠久的一种坝型。近代的土石坝筑坝技术自２０世纪５０年以后得到发展，并促成了一批高坝的建设。目前，土石坝是世界坝工建设中应用最为广泛和发展最快的一种坝型。因农业生产的需要，云南大姚县拟在县城东北7km的金碧镇施永屯办事处龙林村兴建一个土石坝型灌溉水库。在对本处的自然地理与水文特征、工程地质情况及周围的建筑材料了解之后。经过详细的
2、分析之后，选取了坝轴线并进行了枢纽布置。依据毕业设计要求利用内插法进行了调洪演算，得到了设计洪水位与校核洪水位。进行了枢纽布置，划分了工程等级与主要建筑物等级。深入的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、坝身构造设计、输水建筑物设计以及溢洪道布置等十章内容。具体见设计书。关键词：土石坝；调洪演算；输水建筑物。AbstractEarthdamreferstolocalsoilmaterial,stoneormixture,afterthrowingfilling,rollingandothe
