碩士 === 朝陽科技大學 === 營建工程系碩士班 === 92 === The research was carried out by integrating liquefaction-related computer softwares and by developing a data base including subsurface soil bore hole data, regional liquefaction and settlement evaluation/observation in the central Taiwan area after 921 Chi-Chi earthquake. The study was conducted based on the most commonly used liquefaction evaluation techniques with modifications from previous studies on related subjects. An integrated computer software system along with the soil data base were developed in the study to serve as a useful tool for practical applications in liquefaction-related engineering issues in Taiwan. The research was conducted mainly based on (1) Seed’s simplified criteria, (2) strong ground motion study using SHAKE program, and (3) liquefaction settlement evaluation by Ishinara. The developed computer softwares system and soil data base can be easily executed in a PC Window operation system for practical applications. The results of the study revealed that the developed computer software system exhibit accurate rates of from 66% to 85% when compared to the results of field liquefaction investigations on sites throughout the central Taiwan area after the 921 Chi-Chi earthquake. The settlement estimates using the dereloped computer software system were within about 30% of the field observations from the liquefied sites.
