The Study of Risk Assessment of Soil Liquefaction on Land Development and Utilization by GIS in Taiwan

Abstract

The issue of soil liquefaction has been investigated widely in the past 50 years. However, there is no an integrated method have been considered for the factors between regions ’ vulnerability of soil liquefaction and resilience capacity to perform the risk assessment of soil liquefaction hazard. This study selects Yunlin and Chiayi County as a demonstration area, and uses Model Builder of geo-processing models to connect multiple analysis processes, the liquefaction risk distribution in Yun-Chia Plain ’ s area is carried out in 100 (cid:1) 100 m grid map scale by GIS. The study results could provide the reference of land development and management in Taiwan.
