| 摘 要： | 降雨入渗使得非饱和土边坡内含水量增大,进而使土的抗剪强度降低,这是降雨诱发浅层边坡失稳的重要原因之一。在适用于黄土地区的Green-Ampt入渗模型的基础上提出了考虑客土层的入渗模型,并分析了客土对入渗性能的影响。结果表明:客土配比对湿润锋深度和累积入渗量均有较大影响;客土渗透系数对湿润锋深度和累积入渗量都有明显影响,而客土饱和体积含水量只对累积入渗量有较小影响;在模型分析的基础上提出了客土配比所满足的条件。

| Abstract: | Rainfall filtration makes water content in unsaturated soil slope increased and the shear resistance of soil decreased,which is one of the major reasons of shadow slope instability caused by rainfall.In this paper,based on Green-Ampt model applicable for loess area,the filtration model of loess slope considering borrowed soil layer is advanced and the influence of borrowed soil on slope filtration is analyzed.The result shows that borrowed soil proportion has larger influence on wetting front depth and accu... |
