1、摘要土石壩泛指由當(dāng)?shù)赝亮?、石料或混合料，?jīng)過拋填、輾壓等方法堆筑成的擋水壩。當(dāng)壩體材料以土和砂礫為主時，稱土壩、以石渣、卵石、爆破石料為主時，稱堆石壩；當(dāng)兩類當(dāng)?shù)夭牧暇枷喈?dāng)比例時，稱土石混合壩。土石壩是歷史最為悠久的一種壩型。近代的土石壩筑壩技術(shù)自２０世紀(jì)５０年以后得到發(fā)展，并促成了一批高壩的建設(shè)。目前，土石壩是世界壩工建設(shè)中應(yīng)用最為廣泛和發(fā)展最快的一種壩型。因農(nóng)業(yè)生產(chǎn)的需要，云南大姚縣擬在縣城東北7km的金碧鎮(zhèn)施永屯辦事處龍林村興建一個土石壩型灌溉水庫。在對本處的自然地理與水文特征、工程地質(zhì)情況及周圍的建筑材料了解之后。經(jīng)過詳細(xì)的
2、分析之后，選取了壩軸線并進行了樞紐布置。依據(jù)畢業(yè)設(shè)計要求利用內(nèi)插法進行了調(diào)洪演算，得到了設(shè)計洪水位與校核洪水位。進行了樞紐布置，劃分了工程等級與主要建筑物等級。深入的進行了壩體剖面設(shè)計，計算出了壩頂高程。然后又進行了滲流計算、穩(wěn)定計算、細(xì)部結(jié)構(gòu)設(shè)計、壩身構(gòu)造設(shè)計、輸水建筑物設(shè)計以及溢洪道布置等十章內(nèi)容。具體見設(shè)計書。關(guān)鍵詞：土石壩；調(diào)洪演算；輸水建筑物。AbstractEarthdamreferstolocalsoilmaterial,stoneormixture,afterthrowingfilling,rollingandothe
