This research program is part of an ongoing investigation at Treasure Island, California, to investigate the effect of blast loading on structures. This particular project is investigating the difference between blast-induced and earthquake-induced liquefaction. The goal is to learn more about earthquake-induced liquefaction, but since it is so difficult to obtain data during strong earthquake shaking, there continues to be a lot of interest in obtaining data from simulated earthquake conditions, namely via blast-induced liquefaction. The question always is: how accurate is blast-induced liquefaction in simulating earthquake-induced liquefaction? This is the objective of this study.The primary seismic method employed is a crosshole-type measurement, but measurements are also made using the spectral analysis of surface waves (SSAW) technique.

本研究项目是正在进行的加州金银岛研究的一部分，旨在研究爆炸荷载对结构的影响。 这个特别的项目正在研究爆炸引起的液化和地震引起的液化之间的区别。 目标是更多地了解地震诱发液化，但由于在强烈地震震动期间很难获得数据，因此人们对从模拟地震条件下获得数据（即通过爆炸诱发液化）仍然很感兴趣。 问题总是：爆炸液化在模拟地震液化中的准确性如何？ 这是本研究的目的，主要采用的地震方法是井间型测量，但测量也使用表面波频谱分析（SSAW）技术。
