摘　　要：近年来,我国高土石坝迅速发展,水布垭面板堆石坝高233 m,为世界之最,防渗和排渗相结合反滤层保护渗流出口的渗流控制原理得以充分展现,对大坝的经济性和安全性都有重要意义。我国土石坝渗流控制理论的现代水平主要体现在四个方面:①心墙裂缝纳入渗流控制范畴;②面板坝的渗流控制更加完善;③反滤层的作用更显明确;④排水体的作用进一步发挥。High earth-rock dams have been extensively constructed in China.Shuibuya CFRD,233 metres in height,is the highest in the world.The theory of seepage control is adequately developed,and the seepage exit is protected by the filter while seepage prevention is combined with expulsion.It is important for the safety and economy of dams.The development of seepage control theory is exhibited in four aspects：（1） the core crack is included in the study of seepage control;（2） the seepage control of CFRD is improved constantly;（3） the filter works increasingly effectively;（4） the function of drain increases.
