Recently in the civil engineering field, the survey using Handy-Seismograph is getting to popularize connecting with actual works. There are 10 or more kinds of Handy-Seismograph apparatus which have already developed at in and out of Japan. It is a special merit that these any apparatus can be operated by only a few person (one〜three), and are more simple, small size and light weight type as compared with the normal one. The survey by such handy type is named "Shallow Refraction Method" and as the name, it makes to better economy for near surface investigation. And so, it will be a new type of survey technique which holds extensive utilizing sphere, looking at the points of its simplification, movability, original measurement system and so on. Moreover, it will play a part in bringing about understanding among the engineers in field of survey, planning and construction, since whenever, anywhere, anyone can use it. This paper is described as regards the characteristic of apparatus, effectual measurement system, expectant utilization, examples of survey and economical feature, summerizing what writers have experienced heretofore.
