基于MATLAB App Designer的非饱和土壤入渗数值仿真实验研究

Numerical Simulation Experiment of Unsaturated Soil Infiltration Based on MATLAB App Designer

土壤入渗是自然界水分转化的主要过程。文中在分析现有土壤入渗实验教学的不足的基础上,采用数值仿真的方法,建立了非饱和土壤入渗模型,采用MATLAB App Designer开发了非饱和土壤仿真软件。实现了不同条件下土壤入渗过程数值仿真,可有效补充室内试验的不足,使学生全面理解非饱和土壤入渗过程。

Soil infiltration is the main process of water conversion in nature.In this paper,based on the analysis of the shortcomings of the existing soil infiltration experiment teaching,the numerical simulation method was used to establish the unsaturated soil infiltration model,and the unsaturated soil simulation software was developed with the Help of MATLAB App Designer.The numerical simulation of soil infiltration process under different conditions is realized,which can effectively supplement the deficiency of laboratory tests and enable students to fully understand the infiltration process of unsaturated soil.
