Non Destructive in Situ Characterization for Liquefaction Analysis of Soils (Earthquake Hazard Mitigation)

将为进行实地测试实验提供支助 在日本 研究人员已经开发出测量仪器， 原位土壤特性。 地层因素探头用于 表征颗粒和骨料特性，包括测量 力学各向异性 介电-电导率探针提供了 持续监测土壤类型和孔隙度的方法。 这些数据， 结合PI开发的液化分析， 用于对孔隙压力的产生进行先验预测， 在一个网站上的散逸。

Support will be provided for the conduct of field testing experiments in Japan. The investigator has developed instrumentation to measure in-situ soil properties. The Formation Factor Probe is used to characterize the grain and aggregate properties, including a measure of mechanical anisotropy. The Dielectric-Conductivity Probe provides a means to continuously monitor the soil type and porosity. This data, in conjunction with a liquefaction analysis developed by the PI, is used to make a priori predictions of pore pressure generation and dissipation at a site.
