【摘要】：瓦托水電站工程在金河下游河段上,位于昌都市卡若鎮(zhèn)乃帕村金河下游約2.5km處,在已建金河大壩上游約5.0km處,是一座以發(fā)電為主的中型水電工程。水庫正常蓄水位3315.00m,死水位3313.00m,校核洪水位(0.1%)為3317.14m,水庫總庫容0.1383×108m3,電站總裝機(jī)容量為50MW,保證出力8.44MW,多年平均發(fā)電量2.1015×108kW·h。本文對瓦托水電站進(jìn)行了設(shè)計,主要內(nèi)容有:(1)采用皮爾遜Ⅲ型曲線進(jìn)行適線,獲得類烏齊水文站年平均徑流量頻率曲線圖,采用水文比擬法將類烏齊站多年平均流量轉(zhuǎn)換至壩址;采用皮爾遜Ⅲ型曲線適線法獲得昌都站洪峰流量頻率曲線,采用水文比擬法,將昌都站各頻率設(shè)計洪峰流量成果移到壩址斷面;采用同倍比放大法推求設(shè)計洪水過程線。(2)采用抗剪斷強(qiáng)度公式對重力壩門庫壩段進(jìn)行了穩(wěn)定計算,滿足穩(wěn)定要求。(3)利用有限元軟件ANSYS對重力壩門庫壩段進(jìn)行了應(yīng)力分析。計算結(jié)果表明在壩踵處應(yīng)力大于混凝土的抗拉設(shè)計強(qiáng)度設(shè)計值,但與已建成的工程相比,均在正常范圍內(nèi)�？梢圆扇∠鄳�(yīng)的措施避免混凝土開裂,如增加壩踵處混凝土的強(qiáng)度等級、配置鋼筋、設(shè)置壩踵塊等措施來滿足設(shè)計要求。(4)本文對溢流壩閘墩進(jìn)行了配筋計算。取最危險的單寬閘墩(單寬閘墩所受荷載包括:檢修閘門、啟閉機(jī)、軌道的重量及閘墩自重)進(jìn)行計算,中墩采用偏心受壓對稱配筋,邊墩采用偏心受壓配筋,計算結(jié)果均滿足設(shè)計要求。并繪制了重力壩門庫壩段剖面圖和閘墩配筋圖。
[Abstract]:The Wato Hydropower Station is located at the lower reaches of Jin He, about 2.5 km downstream of Jin He village in Nepa Village, Careau Town, Changcheng City, and about 5.0 km upstream of the already built Jin He Dam.
