摘　　要：下沙地区的地基土中含有较厚的粉砂层,且场地周边有鱼塘,需做好充分的防渗措施。本案经地质勘探后运用改进阻力系数法对三号大堤北闸进行渗流稳定计算,选取高压旋喷桩提高防渗能力。水闸建成后通过位移监测对防渗效果进行分析,并对暗塘部位采取防渗补强措施。The foundation soil in Xiasha area contains thick silt layer, and there are fish ponds around the site, so it is necessary to take adequate anti-seepage measures. In this case, after geological exploration, the improved resistance coefficient method is used to calculate the seepage stability of the north sluice of No. 3 embankment, and the high pressure rotary jet grouting pile is selected to improve the anti-seepage ability. After the completion of the sluice, the anti-seepage effect is analyzed by displacement monitoring, and the anti-seepage and reinforcement measures are taken to the hidden pond.
