破砕帯型地すべり地における電気探査の有意性について

Abstract

The electric survey was carried out at some fractured zone type landslides in oder to checkupon the effectiveness of the electric survey at that type landslides.The result was that the electric survey at the fractured zone type landslides were veryeffective survey.Next informations were gotten by the electric survey;I ) Outline of bedrock form of the landslide area2) Existed depth of the bedrock layer3) Thickuess of the slide layer4) Existent conditions of the underground water in the landslide area5) Supposition of the easy movement mechanism of the landslide.
