摘　　要：受地形地质条件限制,我国于20世纪六七十年代在国内采用定向爆破筑坝技术修筑了一批爆破堆石坝,由于爆破筑坝堆石体组成的复杂性,其渗漏非常严重,不能很好地发挥水库功能。结合云南省武定县在20世纪70年代修建的己衣水库定向爆破堆石坝存在的渗漏问题,详细介绍了该水库除险加固防渗处理的设计方案要点,可供从事水利工程设计的技术人员参考借鉴。In the 1960s and 1970s,a number of Blasting Rockfill dams were built,with the direct blasting technology based on the condition of geography. Due to the complexity of the composition,the leakage is a very serious problem. The dams cannot reserve water.The details of Jiyi reservoir and the ways of reinforcing the Blasting Rockfill Dam to avoid the seepage are discussed,which can provide some useful ways of avoiding the Seepage to other engineers.
