[0002] Ground subsidence, also known as land subsidence or land collapse, is a local subsidence movement (or engineering geological phenomenon) caused by the compression of underground loose strata under the influence of human engineering and economic activities, resulting in a decrease in the elevation of the earth's surface. It is a major engineering geological problem in cities around the world. It generally manifests as regional subsidence and local subsidence, which can cause buildings to tilt, damage the stability of the foundation, and cause seawater to back up in coastal cities, causing significant impact on production and life.

[0003] During construction, the ground subsidence needs to be monitored to facilitate the adjustment of construction progress, construction parameters, etc. according to the settlement amount.
