パイプひずみ計について

Abstract

The authors have devised the slide type pipe strain meter which was composed of sensor, guide vinyle pipes and slide mechanism, and have several merits comparing with ordinary type.Namely, it can measure the continuous strain from the surface to the bottom of bore hole, which canconfirm the depth of a slide surface in the case of slide having thin clay layer what we call layerslide type, and so on.The authors measured the slide surface at a landslide area using it, and found the being ofdeep slide surface.
