Abstract

The M 6.4 Meinong earthquake occurred at 3:57:27 a.m. local time on 6 February 2016 in Taiwan (19:57:27 on 5 February 2016 UTC). The earthquake, which took place just before New Year's Eve celebrations for the Lunar Year of the Monkey, killed at least 117 people. Liquefaction damage due to the earthquake occurred in the Shin-Din area in the Annan District of Tainan City. Damage observed in the area includes excessive soil boiling, lateral spreading of a sloped road, and tilting and settling of houses with shallow foundations. Soil profile in this zone is: the first 9m beneath the ground surface is consisted of loose sandy soils and silts with low SPT-N value, and followed by soft clayey soils and stiffer sandy layer to 20m depth. After the earthquake, houses built in continuous shallow foundation were found to experience maximum settlement 15 cm which is less than the ones built in individual shallow foundation experiencing the maximum settlement 120 cm and significant tilt. The main purpose of this paper is to document and analyze geotechnical problems encountered in this region affected by liquefaction.
