摘　　要：通过室内垂直入渗和膜孔入渗试验 ,研究了充分供水条件下膜孔入渗特性 ,建立了充分供水条件下膜孔入渗的 Philip模型 ,分析了膜孔入渗与一维垂直入渗之间的关系 ,可以由一维垂直入渗资料确定充分供水条件下膜孔入渗模型。Film hole infiltration characteristics under adequate water supply are analyzed based on indoor experimental data of vertical infiltration and film hole infiltration, and a Philip model of film hole infiltration under adequate water supply is development. The relationships between film hole infiltration parameters and vertical infiltration parameters are also determined. It is showed that film hole infiltration model under adequate water supply can be determined with vertical infiltration data.
