Soil Liquefaction Potential in Ilan City and Lotung Town, Taiwan

This paper summarizes an evaluation of the soil liquefaction potential in the Ilan County of Taiwan from the geotechnical earthquake engineering point of view. The Lanyang Plain, located in the central part of the Ilan County, is considered an area with liquefaction potential where the subsurface conditions are characterized by loose uniform grained soils and high groundwater table. The evaluation of liquefaction potential provides important information for preventing liquefaction-related damages predicted by earthquakes. The subsurface soil conditions throughout the Lanyang Plain were investigated in detail using boring logs collected from a total of 685 sites. The SPT approach was utilized in this study for the characterization of liquefaction resistance. This paper describes the procedure for constructing the soil liquefaction potential maps of the densely populated Ilan City and Lotung Town within the Lanyang Plain using two scenario earthquakes. These maps can provide information for formulating disaster reduction strategy in order to mitigate damages and losses predicted by the liquefaction hazards.
