Asphalt concrete core-wall dam is one of the main earth-rock dams. It has been widely used because of its many advantages.The paper carried out the calculation of asphalt concrete core-wall dam in Xinjiang by finite element method, analyzed influence of parameters of Duncan-Chang E-u model on maximum horizontal and vertical displacement of asphalt concrete core wall, and provided reference and basis for the parameters selection, calculation and analysis of Duncan-Chang model.
