【正文】 畢業(yè)論文 第 I 頁 共 56，關(guān)系著下游千百萬人民生命財產(chǎn)安全。本設(shè)計主要論述了柳村 水電站 施工導(dǎo)流、導(dǎo)流建筑物的形式、圍堰的 結(jié)構(gòu)設(shè)計及穩(wěn)定分析、混凝土施工等。 柳村電站樞紐 位于 西藏昌都地區(qū)左貢縣境內(nèi)怒江一級支流玉曲河上 ， 為無調(diào)節(jié)壩后式小型水電站。該電站由攔河壩、泄洪建筑物、引水建筑物及電站廠房組成。電站設(shè)計裝機容量為 2 800kW，施工總工期 2 年。 本樞紐導(dǎo)流建筑物為 V級 ， 電站施工導(dǎo)流設(shè)計流量采用平水年平均徑流流量 Q= m3/s 在導(dǎo)流方案設(shè)計時，分別采取了全段圍堰法和分段圍堰共 6 種方案的論述，經(jīng)過技術(shù)和經(jīng)濟論證，最終采用分段圍堰法施工。圍堰材料采用草土袋，土工布防滲，經(jīng)過抗滑穩(wěn)定的分析，圍堰符合設(shè)計標準。 混凝土施工組織 設(shè)計包括混凝土的配制，混凝土的澆筑，混凝土的溫度控制，混凝土的養(yǎng)護，鋼筋及模板作業(yè)等。 柳村電站樞紐為漿砌石硬殼壩 ,混凝土施工主要在電站廠房壩段、溢流面、上游面板及下游消能池。 關(guān)鍵詞： 施工導(dǎo)流，全段圍堰法，分段圍堰法，混凝土施工 畢業(yè)論文 第 II 頁 共 56 頁 Abstract Build the water conservancy project building on the river , is concerning a great amount of people39。s safety of life and property of low reaches . Is it expound the fact Liucun power station construct water conservancy diversion , form , structural design and steady analysis ,concert construction ,etc. of cofferdam , water conservancy diversion of building mainly to design originally. The hydropower station of Liucun lies within the boundaries of Zuogong county of Qamdo Prefecture of Tibet on Nujiang first class tributary Yuqu river, for not regulating the smallscale power station of the type after the dam. Hydropower station by dam, release floodwater building , channel water the building and hydropower station factory building make up. Design installed capacity 2 800kW , always constructs for 2 years of time limit. This pivot water conservancy diversion building V grade, hydropower station construct water conservancy diversion adopt and design the flow of flood crest while being the first stage of , adopt and does not design flow in flood season non while being the second stage of , adopt the intergrity cofferdamdam and hierarchic cofferdamdam methods to 6 argumentation of scheme separately, prove through technology and economy , is it hierarchic cofferdamdam methods to adopt finally. cofferdamdam material adopt grass soil bag, geotechnological cloth prevention of seepage, through is it slip steady analysis to resist, the cofferdam accords with the design standard. The concrete construction anization designs include theconcrete configuration, concrete constructing, the concrete temperature control, concrete maintenance, the steel bar and the template work and so on. The hydropower station of Liucun plants key position for lays with mortar the stone hard shell dam,The concrete construction mainly in the power plant workshop dam section, overflows the flow surface, upstream the kneading board and the downriver disappears can the pond 。 Key Words: River diversion during construction, Intergrity cofferdam method, Hierarchic cofferdam method,Concert construction 畢業(yè)論文 目 錄 前 言 1 柳村水利樞紐施工組織設(shè)計及主體工程施工 2 1 柳村電站工程基本概況 2 水文基本資料 2 洪水 3 洪水特性 3 設(shè)計洪水 3 設(shè)計斷面水位流量關(guān)系曲線 4 地質(zhì) 4 庫區(qū)工程地質(zhì)條件 4 天然建筑材料 7 2 施工導(dǎo)流設(shè)計 183
