The Research of Unsteady Seepage Flow Based on Saturation

摘要：

In this paper, a numerical model simulating the unsteady seepage flow through aquifer was presented and it used two variables: saturation and water head to describe the seepage domain. Experiments of unsteady seepage flow through dam were conducted in laboratory and provided data to verify the model. The performance of the model was also assessed by comparing with analysis solutions. The examples have proved that the accuracy and reliability of the model to deal with seepage flow problems with complex conditions. It also has demonstrated that the method of confirming the seepage face through the saturation description is natural and logical in physical concept and actual application. The method predigested the computing scheme, comparing with those tradition methods.
