This study mainly focus on investigating the liquefaction potential disaster of soil formation located at Fengshan-Taliao section along the orange line of Kaohsiung Mass Rapid Transit。Most of Present Alluvial Formation with high water table in this study area are induced to soil liquefaction easily。However,the "Three-Grade Method of Liquefaction Potential Analysis" techniques which proposed by Ishihara (1993) to estimate sensitive regions of liquefaction disaster in the study area。The investigation and analysis on the potential liquefaction of soil formation by integrating GIS and GPS technology would be necessary in this project。
