摘　　要：通过对土石围堰的特点、分类和我国土石围堰情况的分析,提出了在土石围堰体型的防渗设计中应重视的问题。在设计中除应对投资、进度和安全等问题重视外,还应对环保、拆除方便、抵御超标准洪水、体型和防渗指标选择等有足够的重视。In this paper, through analyses of embankment cofferdam characteristics, embankment cofferdam classification and embankment cofferdam status in China, some noticeable problems in embankment cofferdam seepage control design are pointed out. It is suggested that in embankment cofferdam design, importance should be attached to the investment, construction schdule and safety, besides due attention should be paid to the environmental convervation, convenience for removal, capability to withstand extraordinary flood and selection of the configuration and seepage control indexes.
