“…Chen et al studied the dynamic characteristics and damage law of subway station [21]. Other scholars have also undertaken a lot of research on the dynamic response of various structures and foundations under earthquake using shaking table test and found that the depth and compactness of soil, the existence of structures, and the input parameters of shaking excitation have obvious effects on site liquefaction and dynamic response of structures and soil [22][23][24][25][26][27][28][29][30]. However, the above studies are aimed at the terrigenous sands, and there are few studies on coral sand at present.…”

The physical and mechanical properties of coral sand are quite different from those of common terrestrial sands due to the special marine biogenesis. Shaking table tests of three-story structures with nine-pile foundation in coral sand and Fujian sand were carried out in order to study the dynamic response characteristics of pile-soil-structure system in coral sand under earthquake. The influence of shaking intensity on the dynamic response of the system was taken into consideration. The results indicated that the peak value of the excess pore pressure ratio of coral sand was smaller than that of Fujian sand under two kinds of shaking intensities; moreover, the development speed of excess pore pressure ratio of coral sand was smaller than that of Fujian sand. The liquefaction of coral sand was more difficult than Fujian sand under the same relative density and similar grain-size distribution. The horizontal displacement, settlement, column bending moment, and pile bending moment of coral sand were smaller than those of Fujian sand, respectively. The magnification effect of column bending moment of buildings in coral sand was less than that in Fujian sand with increasing shaking intensity. This study can provide some supports for the seismic design of coral reef projects.

“…Several researches and studies have been conducted related to the impact of liquefaction on residential houses during earthquakes, such as the 2010-2011 Christchurch earthquakes (Cubrinovski et al 2012), the 2011 Tohoku Pacific earthquake (Tokimatsu & Katsumata 2012) and the much earlier study of the 1990 Luzon earthquake (Tokimatsu et al 1994). Various liquefaction countermeasure methods had been proposed, for example, implementing shallow ground improvement (Tani et al 2015), using a sandy soil layer (Koseki et al 2015), installing sheet-pile walls around the housing foundations (Rasouli et al 2015) and by using log pile under foundations (Yoshida et al 2012).…”

Background: In April 2016, Kumamoto City, Japan, and its surroundings were hit by a sequence of strong and devastating earthquakes including two significant events, one on April 14 th , 2016, at 21:26 JST (Mw6.2) and the other on April 16 th , 2016, at 01:25 JST (Mw7.0). These disasters caused 120 fatalities (including indirect fatalities), 2337 people injured and 177,914 residential houses were damaged. This paper aims to ascertain the damage to residential houses and buildings caused by liquefaction during this earthquake and suggests possible mitigation methods. Results: Field reconnaissance was conducted in the target area on May 27 th-30 th , 2016. The post-earthquake inclination angle and the tilt direction of 68 affected houses and buildings in the liquefied sites in Kumamoto City were measured by using a laser rangefinder (Leica DISTO D 510). Ground structure and condition were also determined from topographic maps, bore data and the calculated liquefaction resistance factor, F L. Conclusions: Based on this investigation, the inclination angle of the houses in the target area seems to be related to the type of building structure and their foundation as well to the local ground composition. The tilt direction has a tendency to be associated with the location of the nearby river. The results presented could be useful to develop future liquefaction mitigation measures for detached residential houses.
