With the increasing of the overburden layer thickness or the dam height, the maximum value of response acceleration in dam body assumes gradually decrease, and its characteristic distribution is uniformization, and the response acceleration of the dam slopes decrease remarkably, and response acceleration of the dam top is less than the dam bottom.With the decreasing of the overburden layer thickness, the dam foots and their nearby soil response acceleration get increasing.
