ABSTRACT

The study presents a liquefaction potential analysis for the Thailand-Myanmar border area due to the earthquake. Three sites reported liquefaction during Tarlay earthquake in 2011 were investigated including a microtremor to obtain the shear wave velocity profile and depth of engineering bedrock. Next-generation attenuation model was used to estimate the peak ground acceleration at the liquefied sites. A seismic ground response analysis was then conducted, and the result revealed that the shallow sand layers were very vulnerable to undergo liquefaction. The results also showed a similar tendency to the predictions based on the empirical methods.

泰缅边境强震液化潜力验证

摘要

该研究对地震造成的泰缅边境地区的液化潜力进行了分析。对 2011 年塔雷地震期间报告液化的三个地点进行了调查,包括微震,以获得工程基岩的剪切波速度剖面和深度。下一代衰减模型用于估计液化场地的峰值地面加速度。然后进行了地震地面响应分析,结果表明浅砂层非常容易液化。结果也显示出与基于经验方法的预测相似的趋势。
