过水围堰过水围堰overtopping cofferdam guoshui we一yan过水围堰(overtopping eofferdam)允许堰顶过水的临时挡水建筑物(见施工围堰)。通常有三种类型:土石过水围堰，木笼过水围堰和混凝土围月夏。 土石过水围堰就溢流板护面的材料可分为混凝土板护面、钢筋网护面及石笼护面三种。中国上犹江水电站工程采用了混凝土板护面的土石过水围堰。它高16米，长67米。经多次溢洪考验，单宽流量达32米“·秒一‘·米一‘，过水后实测水平位移接近于零，最大沉陷值0.8厘米，溢水混凝土面板仅有少量破裂。设计时对围堰结构稳定、防渗、抗冲作了周密考虑。为保证堰体稳定，防止堰脚淘刷将混凝土镇墩建在基岩上，底部使用柴排减少不均匀沉陷，面板设置排水孔，有利于消减渗透压力;围堰防渗采用了粘土斜墙、铺盖，并结合以堰顶混凝土及河床覆盖层灌浆。中国大化水电站土石过水围堰采用顺坡式布置，取消了下游挡墙，减少施工干扰。 木笼过水围堰中国新安江水电站曾采用混凝土板护面的过水木笼围堰，堰高12一14米，上游横向围堰长113.2米;纵向木笼围堰长310.6米;下游横向围堰长187 .9米。为改善左岸河槽进出口水流条件，设有上、下游翼堰。木笼的高宽比约为1:1，一般木笼尺寸长6米，宽14.87米，高13米。其中框格平面尺寸采用2.4又2.5米或2.4又3.0一3.5米。根据木笼宽度和长度、纵向分成两格，横向分成4一5格。木笼之间的止水采用柔性橡皮，以适应两格木笼之间的不均匀变形挡水面由两层木板夹两层沥青油毛毡组成，临水面的一格和挡水面板底部浇筑封底混凝土，厚l一1.5米，宽2一3米。顶面用混凝土浇筑在填满石块的木笼上，厚度约1.2米，平时供汽车通行，汛期溢流。 混凝土围堰具有较高抗冲能力，挡水水头高、堰底宽度小，堰顶能溢流等优点。中国刘家峡、乌江渡、风滩等水电站工程都采用混凝土过水围堰。乌江渡水电站上游混凝土拱形过水围堰高达40米，围堰处河面宽35一40米，它是在没有另建土石围堰保护下，直接在水流中建成的。自1972年建成后，经过多次洪水考验，过堰单宽流量70米“·秒一‘·米一‘，均能安全渡汛。 (葛文辉)
