ANALYSIS ON SETTLEMENT OF SOIL DEPOSITS FOLLOWING LIQUEFACTION DURING EARTHQUAKES

[摘要] References(22)Cited-By(4)The procedure for evaluating the settlement of saturated soil deposits following liquefaction during earthquakes is examined, with the effect of grain compositions also taken into effect. The recommended procedure is described in detail, with some revisions and suggestions to the previous study by Tsukamoto et al. (2004b). The use of Swedish weight sounding tests is highlighted for estimating the extent of post-liquefaction settlement. Three case histories involving the post-liquefaction settlement of saturated soil deposits observed during the recent earthquakes are introduced. The use of maximum and minimum settlement potentials, Smax and Smin, is recommended to cover some uncertainty in making evaluations.
