【 摘 要 】

A 3D soil profiling system for effective design of countermeasures for a damaged or potentially damaged river levee is developed. This system consists of a 3D integrated seismic and electric measurement tool and a 3D visualization system of its soil properties such as hydraulic and mechanical properties estimated from the geophysical data. For a quick survey, the 3D measurement tool is a sensor belt with both geophones and electrodes to be able to measure seismic and electric data simultaneously. S-wave velocity and resistivity data acquired by this tool are converted to soil properties such as hydraulic and mechanical properties and support a countermeasure design of levee. In this study, we introduce the experimental result of the 3D soil profiling by using the integrated seismic and electric measurement tool in the field.
