摘　　要：溧阳抽水蓄能电站下库土坝坝基防渗采取振孔高喷防渗墙形式。施工过程中,通过及时调整施工参数,成功地保证了坝体填筑层的墙体厚度。试验检测结果表明,墙体外形尺寸规整、连续性好,渗透系数、抗压强度满足设计规范要求。The jet grouted cutoff wall is used as the seepage control of dam foundation in lower reservoir of Liyang Pumpedstorage Power Station. For guaranteeing the thickness of cutoff wall in dam filled layer, the parameters of jet grouting are timely adjusted during construction process. The test results show that the cutoff wall has a regular shape and size and good continuity, and the permeability coefficient and compressive strength meet the requirements of design specifications.
