宮神地すべり地について(I) ―地温測定調査法の有効性に関する研究―

Abstract

In order to estimate channels of stream of ground water, underground temperature survey in1 meter depth was conducted in the Miyagami landslide area. The diagrams of the distribution oftemperature were compared with the results of electrical resistivity survey and other investigations.The lower temperature parts obtained from such a comparison might show the existing position ofthe channels of vein stream. For purpose of proof of the above point, some draining bore holeswere made toward the parts from a water-collecting well conducted in higher temperature part.When the bore holes reached lowre temperature parts, a large quantity of water gushed out into thewell.This fact might show the usefulness of underground temperature survey in and around land-slide areas.
