摘　　要：对实体式动力机器基础及其周围土体形成的动力相互作用体系在扰力作用下的振动特性进行了分析和研究,发现当有的相邻基础存在时,在一定的基础间距范围内,必须考虑他们振动时的相互影响。The research on the vibration behaviors of the interaction system, which includes single machine foundation, two-machine foundation, combined foundation and soil, are analyzed and investigated. The results shows that the affect of foundations for each other must be considered in close-in foundations, and in some definite separation.
