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.

本文根据1g液化砂土流动试验和离心试验，以及对1964年新泻和科比地震等地震变形的实例研究结果，提出了一种预测液化引起的地面变形的方法。此外，在对科比市地下管线破坏分析的基础上，开发了可液化地基中生命线系统埋地管线的破坏评估程序，并建立了可液化、液化引起的地基变形及其对埋地结构的破坏评估所需的土壤条件和岸壁结构数据库。该数据库被神奈川县政府实际用于地震灾害预防措施。
