摘　　要：以浙江省清溪口水库除险加固工程为例,分析了层切法工艺处治老坝体堆石层后再进行防渗加固的工程效果。针对堆石层中注浆时存在漏浆与坍孔的问题,工程采用了层切法对堆石层进行处治。通过除险加固观测成果的分析,证实了层切法处理堆石层后防渗体施工效果良好。Risk removal and reinforcement project of Qingxikou Reservoir in Zhejiang is taken as an example to analyze the effects of impervious treatment and reinforcement after the layer-by-layer handling of rockfill layers of aging dam body. Without the preliminary treatment, slurry leakage and hole collapse sometimes occur during grouting. Analysis on observation results show that such treatment is effective.
