Liquefaction-induced ground displacement and its related damage to lifeline facilities

Abstract

This paper introduces an outline of liquefaction-induced large ground displacement and the damage to lifeline facilities, and foundations of buildings and bridges piles during the 1995 Hyogoken-Nambu earthquake. Some typical examples of large ground displacements which were measured by aerial survey are presented and the causal relationship of damage to buried pipes and foundation piles with ground displacement is introduced. In addition, the present paper outlines the soil and geomorphological conditions in the areas where the liquefaction and the large ground displacements occurred.
