A model of seepage analysis for heightening planning of a tailings filling dam is constructed by using ADINA,in which seepage field of the tailings filling dam is analyzed.The coefficient of material permeability of the tailings filling dam obtained from inverse analysis is greater than that from laboratory experiment.Seepage free surface from the model is higher than practically measured seepage free surface.The coefficient of material permeability obtained from inverse analysis is more reasonable because the environmental conditions of the tailings filling dam are taken into consideration.After the tailings filling dam is heightened,seepage free surface will become higher,so seepage-proofing equipment and drainage equipment should be added.If possible,surveying equipment for seepage free surface should be added as well.
