【正文】 摘 要J 電站在甌江上游干流梯級開發(fā)的第一級水電站，工程以發(fā)電為主，兼顧航運、放木及防洪等綜合利用要求。甌江流域處浙東南沿海山區(qū)，屬于年調(diào)節(jié)水庫。本次設(shè)計的水庫死水位為 ，正常蓄水位為 283m。根據(jù)歷史洪水資料設(shè)計洪水（P=%） ，水庫的設(shè)計洪水位 。校核洪水位（P=%）為 。根據(jù)地形地質(zhì)的特點選擇壩型為重力壩，壩長 。其中溢流壩段長，其中有 8 孔溢洪道，凈寬 。水電站進水口中心線高程。水電站裝機容量為 18 萬 kW，四臺機組單機 萬 kW。水輪機型號為HL220LJ300；為壩后廠房頂溢流式廠房，開關(guān)站布置在右岸。主廠房總寬定為 19m，總長 68m。水輪機安裝高程為 。起重機選用電動雙鉤橋式起重機，最大起重量選 2100 噸，跨度選用 16m。裝配場長度取 ，進場公路布置在左岸。副廠房是為保證水電站正常運行需要，設(shè)置在主廠房與壩的間隙。主要布置各種機電輔助設(shè)備、房間、生產(chǎn)間和必要生活設(shè)施房間。AbstractJ plant is the first step hydropower station in upper reaches of the Oujiang River. The main purpose of the project is to generate electricity, but also considered the woods of the shipping and protect floods. Oujiang River basin located in the southeast area which is near the say in Zheijang Province, and the plant is a year adjust reservoirThis design determined the dead water level is , the normal water level is 283m. According to the historical flood date (P=%), the designed flood level is , the proofread level is (P=%).According to the characteristics of geology and topography, gravity dam was chosen. The total length of the dam is , and the overflow dam is , and eighi holes overflow causes is set, and the last, the width is 100m. The elevation of the water intake of the plant is .The total electric capacity is 180,000kW,and four generates whose capacity is 45,000kW was installed. The type of the turbine is HL220LJ300. The units are installed in the main power width of the main power house is 19m,the length is 68m. All kinds of auxiliary equipment and other kinds of rooms assemble in deputy house.目錄摘 要 .................................................................................................................................. 1Abstract .................................................................................................................11 水文地址情況與樞紐布置 ..............................................................................................8 流域概況 .........................................................................................................8 水文與氣候 .....................................................................................................8 地形與地質(zhì) ...................................................................................................11 水庫區(qū)工程地質(zhì) .........................................................................................................................11 壩址地質(zhì) .....................................................................................................................................11 天然建筑材料 ...............................................................................................12 土料： .........................................................................................................................................12 砂石料： .....................................................................................................................................12 給定設(shè)計控制數(shù)據(jù) ........................................................................................12 設(shè)計資料 .....................................................................................................................................12 設(shè)計任務(wù) .....................................................................................................................................13 樞紐布置 ........................................................................................................132 重力壩擋水壩段設(shè)計 ....................................................................................................15 剖面設(shè)計 ........................................................................................................15 壩頂高程的確定 ..........................................................................................................................15 壩底寬的確定 ..............................................................................................................................16 實用剖面 ......................................................................................................................................18 荷載計算（取單寬 1 米） ..............................................................................19 設(shè)計洪水位下荷載 ......................................................................................................................20 校核洪水位下荷載 ......................................................................................................................21 穩(wěn)定分析 ........................................................................................................22 設(shè)計洪水位下穩(wěn)定計算 ..............................................................................................................22 校核洪水位下穩(wěn)定計算 ..............................................................................................................22 應(yīng)力校核 ........................................................................................................23 原理 ..............................................................................................................................................23 設(shè)計洪水位下 ..............................................................................................................................24 校核洪水位下 ..............................................................................................................................24 壩內(nèi)構(gòu)造 ........................................................................................................25 壩內(nèi)廊道 ......................................................................................................................................25 壩基處理 ......................................................................................................................................25 壩體分縫 .....................................................................................................................................263 重力壩溢流壩段設(shè)計 ......................
