Frequency content of seismic waves observed in field seismic survey in Korea has almost not exceeded 4kHz(wave length 1m). The limited frequency content not only restricts the minimum size of objects which can be surveyed in seismic tomogrpahic application, but also makes a fundamental limit in the resolution of tomogram. This paper shows the resonable result obtained by confirmimg and resolving the problems which can be occured m measuring procedure for the small - sized section through field application. Seismic tomographic field survey was performed for a concrete construction for railroad bridge in Korea, and to this the tomographic measurements for the stone-build foundation construction for a bell house of church in Germany were compared.
