摘要：

Recently, contactless landslides prognostication systems using light wave lasers and ultrasonic waves have been researched and developed, but they suffer from deterioration of detection accuracy due to environment resistance. To overcome such difficulty, electromagnetic waves have been focused on, and a system which can detect water contents in hydrated soil by electromagnetic waves has been investigated in this paper. As the first step, the measurement of the dielectric characteristics of the hydrated soil and the calculation of the incidence and reflection characteristics of the electromagnetic wave in the hydrated soil were performed as functions of the water content and the operating frequency. And thus, a possibility to prognosticate landslides was indicated by the reflection performance from the hydrated soil at medium frequency band.
