摘　　要：本文通过理论分析及在共振柱仪上粗糙与光滑接触面的对比试验，证实了至少在土的剪应变小于１０（－３）的条件下，土体在粗糙或光滑接触面上都不会发生相对滑移．同时指出了接触面会使与其相邻的一薄层土的动剪模量增大．本文结果对于在相互作用分析中。The cyclic deformation behavoir of interface between soil and structure wasstudied in this paper. The theoretical analysis and experimental results of smoothand rough interface by using a resonant column test device confirm that no slidingoccured along the interface when strain amplitude of the soil is less than 10-3.Moreover it was pointed out that the interface may increase the shear modulus ofthe adjacent soil layer more or less. The results presented would be helpful for modeling interface in the response analysis of interaction between sons and structures.
