| 摘要: |
| 对饱和与非饱和渗流计算的有限单元法进行了推导，并建立了数学模型。通过计算，比较了一般的饱和渗流与饱和一非饱和渗流两种模型的计算结果，并引用模型试验资料进行验证。其结果表明，饱和非饱和渗流计算方法具有不进行自由面调整等优点，在物理概念上更为完善。 |

| Abstract: |
| This paper gives the detailed derivation of mathematical model for saturatedunsaturated seepage computation by FEM. On the basis of computation the results of two methods i. e. saturated seepage and it with unsaturated seepage are compared. Also their results are verified by data of hydraulic model test. After comparison the method of saturated-unsaturated seepage computation gives physical conception perfectly without adjustment for free surface. |
