一维稳态入渗时非饱和土基质吸力分布
摘要:雨水的入渗和蒸发对土体的其质吸力分布有着重要的影响作用。利用水相连续性条件、广义Darcy定律及Gardner关于非饱和土导水系数和基质吸力的经验公式，建立并求解出非饱和土一维稳态渗流情况下基质吸力沿深度变化的关系表达式。根据所解得的解析解，详细分析了在单一土层情况下参数α、入渗强度q和qlks对基质吸力分布的影响。
Abstract:Infiltration and evaporation has great influence on matric suction distributions. Based on water phase continuity requirenent,generalized Darcy's law and Gardner's empirical equation on relationship between coefficient of hydraulic conductivity and matric suction, formulas are established and solved to calculate matric suction distribution in unsaturated soils in the condition of onedimensional steady-state infiltration and evaporation. In single unsaturated soil system, an analytical parametric study is carried out. Parameters,include α,infiltration rate q and q/ks,are considered in the study.
