摘　　要：高压旋喷桩在建筑物地基加固、水库大坝坝基截渗中有着广泛的应用,但在水库高水位情况下渗水强的砂砾质施工围堰及堰基防渗中则少有应用。文章就此种情况下施工围堰综合防渗设计及高压旋喷桩截渗技术的成功应用进行了介绍,以期对类似情况的施工防渗提供参考。High pressure rotary jet grouting pile is widely used in building foundation reinforcement and reservoir dam foundation seepage interception,but it is seldom used in sand and gravel construction cofferdam and dam foundation seepage prevention under the condition of high water level of reservoir.Briefly,this paper introduces the comprehensive impermeable design of cofferdam construction and the successful application of high pressure rotary jet grouting pile seepage cutting technology in this situation,with expectation to provide reference for similar inpermeable construction.
