A BASIC EXPERIMENT ON LIQUEFACTION OF SANDY BEACH WITH ARTIFICIAL VEGETATION

Abstract

 In recent years, social interest in Eco-DRR (Ecosystem-based Disaster Risk Reduction) has been increasing as a disaster prevention and mitigation measure utilizing ecosystems. This Eco-DRR is not to consider both the development by hardware measures accompanying disaster prevention and the environmental protection as the opposing axes, but to take advantage of both, and to show the significance of green infrastructure development. It is considered that the sandy beach has a potential expression function. In this study, we conducted a liquefaction experiment using artificial vegetation on the sandy beach along Awaji Island, and examined the liquefaction characteristics of the sandy beach depending on the existence and type of vegetation.
