This project carries out field measurements of seismic responses of ground motion and pore pressure buildup in a seismically active site in Lotung, Taiwan. The Lotung site is in a seismically active region prone to large earthquakes and has potentially liquefiable soil deposits at shallow depths below the ground water table. Additional field instrumentation for this project will include the installation of pore pressure transducers at depths up to 20 meters below the surface. Laboratory testing of soil samples from the site will be made to characterize the dynamic soil behavior. ;itA priori;ro analysis will be developed to predict the pore pressure responses to soil. The analysis results will be compared with actual field data.

该项目对台湾罗东地震活动场地的地面运动地震响应和孔隙压力累积进行现场测量。 罗东遗址位于地震活跃地区，容易发生大地震，并且在地下水位以下的浅层深处存在潜在的可液化土壤沉积物。 该项目的其他现场仪表将包括在地表以下 20 米深处安装孔隙压力传感器。 将对现场土壤样本进行实验室测试，以表征动态土壤行为。 将开发先验 ro 分析来预测土壤的孔隙压力响应。 分析结果将与实际现场数据进行比较。
