| Research Abstract |
A method for prediction of liquefaction-induced ground deformation was developed based on flow tests of liquefied sand under 1g and centrifuge conditions, as well as on the results from case studies on the ground deformations during past earthquakes such as the 1964 Niigata and Kobe earthquakes. Furthermore, a damage assessment procedure of buried pipes of lifeline systems in liquefiable ground was also developed based on the analyses on the damage to pipelines in Kobe city.
On the other hands, a date base of soil conditions and quay wall structures was developed for the assessment of the liquefaction, liquefaction-induced ground deformation and its related damage to buried structure. This data base was practically used for the earthquake disaster prevention measures by the Kanagawa prefectural government.
