摘要

[目的] 为进一步认识层状土垂直一维入渗土壤水分运动规律。[方法] 依据非饱和土壤水分运动理论

建立了垂直一维土壤饱和-非饱和水分运动的数学模型

并用SWMS-2D软件进行求解。采用已有文献资料

对均质土和层状土的土壤剖面含水率、土壤湿润锋运移值和累积入渗量及入渗速率等指标的实测值与模拟值进行分析验证。[结果] 实测值与模拟值具有较好的一致性

所提出的数学模型既适用于均质土壤

也适用于层状土壤。[结论] 所建模型能比较真实地反映均质土和层状土垂直一维入渗土壤水分运动的状况

证明利用SWMS-2D软件对层状土柱中土壤水分运动进行模拟具有可行性。

Abstract

[Objective] To understand the soil water movement in vertical one-dimensional infiltration in layered soil.[Methods] A mathematical model for soil saturated and unsaturated water movement in vertical one-dimensiona was established based on unsaturated soil water movement theory

and the SWMS-2D software was used to solve the model. Using the existing literature

the simulation results of homogeneous soil and layered soil were verified by the measured values of soil moisture content

soil wetting front

cumulative infiltration and infiltration rate in laboratory test.[Results] The simulation result agreed well with measurement values

and the proposed numerical model is applicable to both homogeneous soil

and layered soil.[Conclusion] The model can truly reflect soil water movement in vertical one-dimensional infiltration in homogeneous soil and layered soil. The SWMS-2D software can be used to simulate the soil water movement of vertical one-dimensional infiltration in layered soil.
