タイトル(英): STUDY ON RISK MAP OF LIQUEFACTION CONSIDERING A DISTRIBUTION OF GROUND DATA IN SPACE
抄録(英): In order to evaluate risk of liquefaction in earthquake, a mesh of divided area is frequently used with GIS (Geographic Information System). But all meshes has not a boring log, their area cannot be evaluated the risk of liquefaction. Authors interpolated boring logs (stratigraphy, thickness of a bed and N-values) with a geostatistical method (Kriging). A distribution function of N-value can be derived from the relationship between N-value and effective overburden pressure. Probabilities of liquefaction of all meshes can be calculated with Monte Carlo method, and compared with evaluation of PL-value.
