二维渗流场的MATLAB仿真在土力学教学改革中的应用

The MATLAB simulation of 2D seepage field and its application in education reforming for the soil mechanics

分析了二维渗流场与二维温度场之间的相似性,基于许多实际工程中的渗流问题都可视为平面应变情况,提出利用M at lab软件的热分析功能进行非饱和土渗流的计算方法,阐述M at lab软件中的PDE(偏微分方程)工具箱在求解计算流体力学问题中的应用过程,算例结果表明应用M at lab软件进行非饱和土渗流场的数值模拟是可行的,可以满足土力学关于渗流的章节教学改革需要。

The comparability between 2D seepage of field with 2D temperature field was analyzed , the planar strain model suits many engineering problems, a new method was proposed to improve the calculation of seepage problem which makes use of the module for hot analysis in Mat lab , elaborate the PDE Toolbox usage process in the Mat lab, The result of an example showed that method which the author presented is viable, so it can satisfy the demand of education reform for the chapter about seepage in the soil mechanics and achieve better teaching effect.
