| Abstract: | Various approaches of study on the interaction of the rockfill dam foundation system have been introduced and examined in this paper.The feasibility of direct transplantation of the approaches to the study on the interaction between concrete dam and foundation to the study on the interaction between soil and structure systems is questioned due to the non linearity of both the structure and the foundation.Such problems as artificial boundary and seismic input mechanism involved in the interaction study are discussed in detail,as well.Finally,the prospects of the study are predicted. |
