摘要

In Japan, many remediation methods against liquefaction have been developed since the 1964 Niigata earthquake. The methods are classified into two categories: Ground treatments to prevent liquefaction, and measure that strengthen structures to prevent or minimise damage if the ground liquefies. The remediation methods have been applied to many kinds of structures, such as oil tanks, quay walls, bridges and buildings. The effectiveness of ground treatments in preventing liquefaction has been proved during past earthquakes. However, the 1995 Kobe earthquake presented three problems: The applicability of current methods under very strong shaking (Level 2 earthquake motion), the introduction of a new design concept based on performance, and countermeasures against liquefaction-induced flow. Many studies on these problems have been conducted recently in Japan.
