Development of FDEM and applicability to river embankment survey

Abstract

When survey of the stability of river embankment, it is often that analyze it in several boring findings. It is concerned in the stability that was analyzed when embankment materials is different from the boring results, and there was the partially weak points of embankment materials. Frequency domain electromagnetic method (FDEM) can survey resistivity and is advantageous in that can survey quickly, continuously and high accuracy in the long section. This study examined applicability of FDEM and the principle of the FDEM and the result of survey in river embankment.

Application of Microtremor Measurement for Estimate of Overall Stiffness of Levees

“…Based on the correlation between resistivity and condition of soils, it may be able to detect weak section of levees [4]. A surface wave method can detect shear wave structure of levees by measuring surface waves traveling along the levee [3].…”
