摘要
对土石坝地基相互作用的研究进展作了简要回顾，并对各种研究理论进行了评述，同时对将混凝土坝地基及土结构相互作用问题的研究手段，直接移植到土石坝地基这种结构和地基都呈强烈非线性的研究的可行性提出质疑．重点对相互作用研究中的人工边界及地震输入机理问题进行了详尽的论述．最后。
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.
