Unsaturated sharp wetting front model based on Mein-Larson saturated infiltration model

Department of Geological Engineering, Chang';an University, Xi'an 710054, China

摘要

摘要: 降雨入渗模型在渗流理论、地质灾害评价等方面具有重要的理论意义及工程应用价值。基于饱和入渗的Mein-Larson模型及李宁等学者提出的非饱和入渗模型,利用非饱和土的Van Genuchten水土特性及渗透系数模型,提出了简化的非饱和锐利浸润锋模型,用以分析均匀含水率土体及含水率随深度变化的土体,其含水率、浸润深度、吸力等随雨强、降雨持时的变化。通过3种模型在不同工况下与有限元模拟结果进行对比,验证了本文提出的模型能更好的描述黄土中的非饱和水分迁移。

Abstract: The rainfall seepage model is of theoretical significance and engineering application value in the seepage theory and assessment of geological hazards. Based on the Mein-Larson saturated infiltration model and unsaturated uniform infiltration model proposed by Lining and other scholars, an unsaturated wetting front model is proposed using the unsaturated soil water characteristics and hydraulic conductivity model proposed by Van Genuchten to analyze the water content, depth of infiltration and suction changing with the rainfall intensity and duration under the assumption of the soil moisture uniformly distributed and changing with depth. Meanwhile through the comparison between theoretical models and Seep/w simulation under different rainfall conditions, the proposed model is found to exhibit advantages in describing unsaturated water flux in loess.
