帷幕
curtain
WelmU帷幕(curtain)沿坝基及其两岸延伸部分的地下连续防渗幕体.它是常用的坝基防渗措施之一帷幕与挡水建筑物的防渗结构的可靠连接，共同形成地上、地下连续的防渗体系.用钻孔灌水泥浆或各种化学浆液形成的帷幕称灌浆帷幕(见帷幕灌策和化学灌泉).在砂砾石坝基中用泥投土防渗堵形成的帷幕称垂直防渗J.帷幕(见软基处理)。在防渗墙下进行灌浆的帷幕称组合式帷幕。帷幕的作用主要有:①减少坝基和绕坝渗漏量。②防止断层裂隙中的充填物及抗水性能差的岩层产生管涌。③在帷幕和排水的共同作用下，使幕后坝基及两岸边岸的渗透压力降低至允许值，防止渗透压力对坝体、坝基及两岸边坡稳定产生不利影响。④灌浆帷幕兼有对坝基表层的接触灌装和固结灌泉的作用。 帷幕的深度和伸人两岸的范围由坝高、地质条件及防渗要求等确定。帷幕深度一般伸人相对隔水层以下3~sm;伸人两岸的范围一般至正常蓄水位与天然地下水位相接处。帷幕范围也可根据地质条件及防渗要求，经计算或试验确定.通常帷幕深度多为0.3一。.7倍水头.相对隔水层考虑坝高、坝型、地质条件等因素，以钻孔压水试验透水率q<1~10 Lu(吕荣)为标准。岩溶地区的帷幕深度及伸入两岸的范围，应根据岩溶及渗漏通道的分布情况和防渗要求确定。伸人相对隔水层的帷幕称封闭式帷幕。未伸人相对隔水层的帷幕称悬挂式帷幕. 帷幕灌浆的钻孔方向有垂直的和倾斜的。帷幕钻孔的排数有单排的和多排的.倾斜帷幕在一定地质条件下，能穿过较多的岩体裂膝和层面，有时比垂直帷幕的防渗效果好，但对钻孔施工要求较高。单排孔帷幕适用于岩体完整性良好透水性弱的坝基;当帷幕承受水头较高或裂隙发育、岩体透水性强时，可采用多排孔帷幕。 当水头较高时，为保证帷幕质量和方便施工，两岸帷幕沿坝基按30~50m高差分层布置和施工，上、下层帷幕搭接处采取浅孔灌浆等措施以保证其可靠衔接。
