[0002] Among many geological disasters, ground subsidence is a relatively common natural disaster. The occurrence of ground subsidence is not only the result of natural factors, but also has many human factors. In the standard definition, ground subsidence refers to the vertical downward movement of the earth's surface under the influence of natural and human factors. There are many factors that cause ground subsidence, among which the natural factors are mainly tectonic uplift and movement, earthquakes, volcanic activity, etc. Human factors are mainly the exploitation of groundwater and oil and gas resources and the increase of local load. The ground subsidence caused by natural factors has a large range and a small rate. However, there are also many human factors, and the ground subsidence caused by human factors generally has a smaller range but a larger rate and amplitude. Generally, the ground subsidence caused by natural factors is classified as crustal deformation or tectonic movement, and is studied as a natural dynamic phenomenon. The ground subsidence caused by human factors is classified as a geological disaster phenomenon and is studied and prevented.
