Abstract

This paper describes developing profiles of liquefaction potential of subground section as a kind of geotechnical characteristics by applying the prediction method for FL value and by using regional geological and geotechnical subground data. In order to verify the applicability of liquefaction prediction methods specified by design codes in Japan, liquefaction of the ground in Inazawa City, Aichi prefecture, induced by 1944 Tohnankai Earthquake is discussed by means of FL values for a few geological subground sections in that area.

The profiles of liquefaction potential subground section reveal high liquefaction potential zones for specified maximum ground surface acceleration. These subground sections are available as geotechnical informations in advance to ground surveying for foundation designs of structures.
