Abstract

To take advantage of ANSYS/APDL optimization technology, combined with engineering geological and hydrogeology data as well as drilling data, seepage parameters of dam area are back-analyzed; seepage model of natural seepage field, boundary conditions and permeability coefficient are obtained, which are compared with the results of drilling and test. All of these provide the reference for the research of seepage control scheme during construction and operation.
