破砕帯地すべり地の地中内部歪計観測の2・3の問題について

Abstract

Many data of the internal strain meter of the shattered zone type landslide areas are collected, and availability of these data studied from the testimonys of laboratory works, geological phenomenaand slope displacement.The writers are pointed out some problems of the internal strain meter survey. They are thehard questions of the charge of the space between bore hole and internal strain meter, and station-ing intervals of strain gauges, and discordance between the shape of pipe and the pillar-shaped graphof accumulated strain, and etc.
