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 ensure the flood control safety of the embankment in the lower Yellow River, in recent years, projects of desilting and solidifying the dikes have been carried out on both sides of the Yellow River dikes. Shed back body soil permeability has important engineering significance. Based on the analysis of infiltration test parameters of embankment dredging soil in the lower reaches of the Yellow River, the statistical indexes and their distribution rules of infiltration test parameters for the soil in the dredging back engineering are obtained, and their application in seepage stability reliability theory Research silt back body reasonable width and height of the specific application.
