Title:
SUBSIDENCE MEASUREMENT SYSTEM, AND SUBSIDENCE MEASUREMENT METHOD
Document Type and Number:
Japanese Patent JP2023120497
Kind Code:
A
Abstract:
To provide a subsidence measurement system and subsidence measurement method that can grasp an amount of subsidence of a structure such as a support and the like in real time.SOLUTION: A subsidence measurement system comprises: a reference tank 16 that accommodates a measurement-purpose liquid; differential pressure detectors 18 that are installed at measurement points P set respectively in a structure (a support 14) and a ground G, and outputs, as a differential pressure signal, a pressure difference between pressure of the accommodated liquid and prescribed reference pressure; pressure guide pipes 20 that allow the reference tank 16 and the differential pressure detectors 18 to communicate with each other; computation means 22 that has an amount-of-subsidence computation unit 22A obtaining height differences each between a reference surface and each measurement point P on the basis of the differential pressure signals from the differential pressure detectors 18, and computing an amount of subsidence of the measurement point P from the difference in height, and an amount-of-deformation computation unit 22B computing an amount of deformation of the structure (the support 14) due to the subsidence; and presentation means that responds to a request from a user to present a computation result by the computation means 22 to a terminal 24 on a user side.SELECTED DRAWING: Figure 1
