2024年12月31日 · Verified against local field investigation data in Taiwan, rapid imaging through post-earthquake remote sensing data can effectively assesses the distribution of coseismic landslides and soil liquefaction within high-intensity zones. This study provides efficient and reliable data for earthquake disasters response.
Taiwan Ground Failure Database - University of California, Berkeley
The Chi-Chi, Taiwan earthquake represents an important source of case histories, including hundreds of structures that settled and tilted due to liquefaction and ground softening. Study of these case histories will enable earthquake engineers to develop much-needed, rational analysis and design procedures to address hazards posed by ground failure.
The purpose of this paper is to present the geotechnical investigation results of some liquefaction sites in central Taiwan, including Nantou City and Zhanghua County during Chi-Chi Earthquake, 1999.
Evaluation of soil liquefaction in the Chi-Chi, Taiwan earthquake using ...
2004年10月1日 · During the 1999 Chi-Chi, Taiwan earthquake, many sand boiling phenomena were observed in central Taiwan, which caused severe ground settlement and structure damages. According to the installed accelerograms, the peak ground surface horizontal accelerations in the liquefaction-affected areas range from 774.42 to 121.3 gal.

Liquefaction is a soil behavior phenomenon in which a saturated soil losses a substantial amount of strength due to high excess pore-water pressure generated by and accumulated during strong earthquake ground shaking.
Liquefaction-Induced Lateral Spreading in Near-Fault Regions …
2006年12月1日 · We document and analyze incidents of liquefaction-induced lateral ground deformation at five sites located in the near-fault region of the 1999 Chi-Chi Taiwan earthquake. Each of the lateral spreads involved cyclic mobility of young alluvial soils towards a …
