Abstract: The dynamic response characteristics and anti-seismic performance of high earth-rock fill dams, are the overriding concern in dam engineering area. Confirmation of the ground motion input is the primary work for dam structure dynamic analysis, and the important influential factor on accuracy of the analysis. In this paper, the main topics related to the study on method of ground motion input in the dynamic analysis of earth-rock fill dam are discussed, and the study situation of these problems is generalized and reviewed. Some problems which need to be studied further are presented too.

Key words: hydro-structure, dynamic analysis, earth-rock fill dam, ground motion inputting, overview
