摘　　要：准确掌握土中渗流场特征是研究土的变形、强度及渗透稳定性的前提基础,是土力学课程的核心教学内容之一。在分析土力学课程中平面二维稳定渗流场方程及其教学难点的基础上,利用数值模拟软件FLAC3D模拟分析了均质各向同性、均质各向异性以及各向同性成层土的渗流场特征,并在课堂上现场展示了各种地基土性质时的孔隙水压力以及流速矢量的分布特征,使得课堂教学更加生动形象。The accurate grasp of the characteristics of the seepage field in the soil is not only the prerequisite for thestudy of the soil deformation,strength and permeability stability,but also one of the core teaching contents of the soilmechanics course. On the basis of analyzing the plane stable seepage field equation and its teaching difficulties in thecourse of soil mechanics,the seepage field characteristics of isotropic,anisotropic and isotropic layered soils are simulatedand analyzed by FLAC3D.And the distribution characteristics of pore water pressure and velocity vector of variousfoundation soils are shown in the classroom,which makes the classroom teaching more vivid.
