Abstract The changes of earthquake acceleration in bed rock after transiting in horizontal soil layers are calculated by using the method of equivalent linearization. The influence of frozen earth layers and radiant damps of groundwork is considered and back-analysis is performed. The results indicate that the factors of radiant damps of groundwork and changes of seasons should be considered in seismatic design of structure.
