摘　　要：为了保证黄河下游大堤的防洪安全,近些年来,在黄河堤防两侧背河进行了放淤固堤的工程。淤背体土质的渗透特性具有重要的工程意义。通过对黄河下游堤防淤背土体的渗透试验参数进行分析,得出了用于淤背工程设计中土体的渗透试验参数统计指标及其分布规律,并介绍了其在利用渗流稳定可靠度理论研究淤背体合理宽度及高度中的具体应用情况。In order to insure flood prevention around the lower Yellow River downstream dyke, dyke strengthing by desilting recently is put into practice on both sides of the river wail. Soil permeability of dyke strengthing by desilting is important for engineering. By analysis of soil permeability test data of dyke strengthing by desilting, we have obtained soil permeability test data statistical index and distribution rule. And the paper introduces research application of width and height of dyke strengthing by desilting by using reliability theory.
