Abstract: Most of the earth-rockfill dams in China were built in the 1950s and 1960s. Due to poor technology and construction conditions at that time, many reservoirs have leakage problems. Taking Longquan reservoir in Dalian as an example, this paper introduces the application of high pressure jet grouting in seepage control of earth-rockfill dam, for reference.

Key words: earth-rockfill dam, seepage control, grouting

摘要： 国内土石坝大多建于20世纪五六十年代，受当时技术、施工条件影响，许多水库存在大坝渗漏的安全隐患，或多或少需要防渗加固处理。以大连市驼山乡龙泉水库为例，探讨高压喷射灌浆在土石坝防渗中的应用。
