摘　　要：分析了仁宗海水电站悬挂式混凝土防渗墙在坝体填筑期间的墙体挠度、墙体上下游不同高程的渗压变化及墙体沿深度的垂直向应变规律,认为墙体挠度与坝体填筑有关,受坝体自重产生的水平推力作用影响明显;防渗墙防渗效果良好,但存在渗流绕过墙底向下游渗透;竖向荷载及墙侧摩阻力对防渗墙应变空间分布特征有较大影响,浅部墙体垂向应变为拉应变,随着墙体深度增加,拉应变减小并转化为压应变,最大应变出现在墙底附近,表现为受压。By analysis on the monitoring data of suspended concrete impervious wall under construction of Renzonghai hydropow-er station,including the wall deflection,seepage pressure of different elevation upstream and downstream the wall and the verti-cal strain along the wall depth,conclusion was gotten that the wall deflection was related to the dam filling,and largely effected by the horizontal thrust caused by dam body weight.The impervious wall was effective,but by pass seepage was found towards downstream.Vert...
