EXPERIMENTAL STUDY ON DEFORMATION OF RUNWAY INDUCED BY LIQUEFACTION IN AIRPORT CONSTRUCTED IN WATERFRONT RECLAIMED LAND

Abstract

Full-scale experiment using controlled blasting was conducted in the Ishikari Bay New Port (Ishikariwan-shinko) in Hokkaido Island, Japan, to assess the performance of airport facilities subjected to the liquefaction. This paper mainly describes effect of liquefaction remediation and behavior of runway pavement during and after liquefaction by optical fiber monitoring.
As a result of Full-scale experiment, a lot of valuable knowledge was obtained. Especially three types of tried liquefaction remediation with cost reduction deign specification are effective. Additionally optical fiber sensor shows high possibility for utilization as a runway pavement performance monitor because its deformation induced by liquefaction could be measured.
