Geotechnical Information Construction Methods for Liquefaction Assessment

Conference paper
Part of the Lecture Notes in Civil Engineering book series (LNCE, volume 62)


The liquefaction is a phenomenon that the ground lost shear strength by the effective stress becoming 0 due to the rapidly built up excess pore water pressure when an earthquake acts on the ground. Liquefaction can be assessed by the factor of safety defined by the ratio of the cyclic resistance ratio (CRR) to the cyclic shear ratio (CSR), and the scale of liquefaction damage is assessed by Liquefaction Potential Index (LPI). The LPI can be determined by geotechnical information. However, the geotechnical information that can be obtained by in-situ tests or boring information have an issue of the representative of the target area. The issue of the representative is can be handled with geostatistical method. The kriging was used for the spatial interpolation. Therefore, this study proposes a construction method of geotechnical information database (DB) for determining the LPI with spatial interpolation technique.
