EXPERIMENTAL STUDY ON COUNTERMEASURE FOR LIQUEFACTION TO RUNWAY PAVEMENT IN AIRPORT SITE

Abstract

  Securing an airport function during and after a great earthquake is very important from the viewpoints of emergency medical service and special operation for transporting relief supplies to disaster areas. However, it is difficult to estimate the damage to airport facilities by a great earthquake. In this study, full-scale field experiment using controlled blast technique was carried out to assess the performance of airport facilities constructed in waterfront soft ground subjected to the liquefaction. This paper describes the effectiveness of countermeasure for liquefaction to the runway pavement based on the observational results of the liquefaction behavior of runway pavement and the damage analysis of the runway pavement on the improved and the unimproved ground.
