電気探査による地すべり防止工事の効果判定について ―串林地すべり地―

Abstract

We carried out repeated surveys, using the electrical resistivity method, at each stage of aserses of landslide preventive engineering works, as one means of making it possible to operate thenecessary works in the most effective way when landslide preventive enginnering works wererequired for the specific purpose of draining the underground water contained in the landslide area.B:sides, by carefully weighing our surveyed results obtained at each stage of the preventiveengineering works, we proceeded to determine the merits and demerits, or effectiveness, of thepreventive engineering works at each given stage of operation, and we tried to utilize our surveyedresults obtained at given stages in deciding whether there is any necessity of making any adjustmentsor modifications for forthcoming preventive engineering works.
