METHOD AND APPARATUS FOR MEASURING AND VISUALIZING LIQUEFACTION PHENOMENON USING SPECIFIC RESISTANCE

摘要

PROBLEM TO BE SOLVED: To provide a measuring method capable of directly measuring the porosity and the relative density of a layer of saturated sand in real time and visualizing a liquefaction phenomenon and a measuring apparatus for use. SOLUTION: The method for measuring and visualizing liquefaction phenomenon using specific resistance visualizes the liquefaction phenomenon within a layer of saturated sand by making a graph of the relationship between a value of specific resistance and time, at each of measuring positions at each of plural points within the layer of saturated sand to which vibration was imparted.
