SGER: Monitoring Stiffness of Soil Following Blast Induced Liquefaction at Treasure Island, California

这个研究项目是加州金银岛正在进行的一项调查的一部分，目的是调查爆炸载荷对结构的影响。这个特别的项目是研究爆炸引起的液化和地震引起的液化的区别。我们的目标是更多地了解地震诱发液化，但由于在强烈地震中很难获得数据，因此人们对从模拟地震条件下获得数据继续感兴趣，即通过爆炸诱发液化。一直以来的问题是：在模拟地震液化时，爆炸液化的准确性如何？这就是本研究的目的。采用的主要地震方法是井间测量，但也使用表面波频谱分析（SSAW）技术进行测量。

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.
