000019419 520__ $$2eng$$aMany urban areas in Taiwan are located in the alluvial deposit with high ground water level which is prone to soil liquefaction endangering buildings, transportation and lifeline systems under strong ground shaking. An extensive database of engineering boreholes from the governmental agency and private sectors is established for soil liquefaction analysis. An automatic processing module producing the shake map and soil liquefaction map in a 500m × 500m mesh is developed in this study. The Meinong earthquake (M L =6.6) in 2016 caused 117 death and wide-range soil liquefaction was chosen as a case study to verified the performance of the methodology. Incorporated with the actual distribution of ground motion and the borehole data in corresponding grids is capable of providing a superior evaluation of liquefaction potential comparing to traditional approach subjected to a uniform excitation. The analytical results of liquefaction potential and induced settlement are generally consistent with the field observations except for some areas without borehole data. Majority of the buildings settled obviously as a result of soil liquefaction are seated in the medium liquefaction potential region as the analysis disclosed. This study provided the prompt and reliable information to the commander for decision making in the practical emergency operation.
