Apparatus and method for measuring ground subsidence using pressure gauge

Abstract

The present invention relates to an apparatus and a method for measuring ground subsidence using a pressure gauge, in which the apparatus includes: a plurality of pressure gauges installed along a ground surface at a subsidence reference point of ground and a plurality of measurement positions to be measured, respectively, to measure a pressure displacement at each of the measurement positions; a pressure transmission pipe filled therein with a liquid supplied from a tank installed at the subsidence reference point to transmit a pressure to each of the pressure gauges; and a measurement terminal connected to each of the pressure gauges through an optical cable, and configured to convert the pressure displacement measured by each of the pressure gauges into a height displacement to measure an amount of the ground subsidence.
