| dc.description.abstract | Taiwan is located at the boundary of the Philippine Sea Plate and the Eurasian Plate, earthquakes caused many buildings to be damaged and loss of life and property. They also trigger soil liquefaction, leading to an increasing awareness among the public about this phenomenon. To evaluate liquefaction hazard, Iwasaki et al. [1] proposed three levels of liquefaction hazard based on the Liquefaction Potential Index (LPI). However, the classification of liquefaction hazard cannot be quantified and other scholars have proposed different ratings for liquefaction potential hazard, there is no standard value for it. Therefore, the study is to transform the probability of soil liquefaction from a classification to a quantitative standard and use the data from the Taipei area and the Sanchiao fault for analysis. The analysis will also incorporate Ground Motion Prediction Equations (GMPE) to estimate the size of ground motion and calculate the probability of soil liquefaction within the specified timeframe.
The study is used for calculating soil liquefaction probability on a time-based deterministic method, based on the liquefaction probability (PL) proposed by Liao et al. [2], and used 509 liquefaction cases in Taiwan to develop a new liquefaction probability model suitable for local conditions, and we did not consider the uncertainty of variables to conduct time-related analysis. Finally, we used this method to conduct a case study in Taipei and calculated the probability of soil liquefaction in the next 25, 50, 100, ..., and 1000 years after an earthquake.
The study is to evaluate soil liquefaction probability based on time. The calculated liquefaction probability is an actual value, which is different from classification results that cannot determine the probability of liquefaction. Risk assessment is defined as the probability multiplied by the consequences of an event, the calculated probability of soil liquefaction means that further risk assessment can be carried out in the future. | en_US |
