This paper attempts to compute the coefficients of subgrade reaction from which the supporting capacity of piers can be estimated, using dynamic responses of energy applied to the vertical axis of piers In order to evaluate the safety of piers To compute the coefficients of subgrade reaction, we built up a standard pier, using elastic springs already known which would represent a real condition of ground We also induced a general relation expression between coefficients of subgrade reaction and eigen value, from numerical formula. After experiments regarding to dynamic responsive properties of a real standard pier, coefficients of subgrade reaction were computed by substituting dynamic properties for the general relation expression. Comparing those results and experimental data, we proved the usefulness of the general relation expression induced in this study
