%X Based upon in-situ measured data of seepage of Fengman concrete gravity dam and making use of the least square method, the permeable coefficients of the concrete dam and rock basement are identified. The seepage fields are studied with finite element method based on the identification results of aquifer parameters. The free surface positions are determined with compressing mesh method and iteration procedure. Aquifer parameter identification is made by means of iteration procedure. The search directions are determined with Levenberg-Marqua- rdt procedure. The practical application shows that the presented study of three dimensional seepage field with free surface and the identification procedure of aquifer parameters are available.
