The ground cracks are of various types, and the prevention and treatment methods are different. The tectonic ground cracks such as earthquake ground cracks, tectonic creep ground cracks and the like are mainly controlled by the motion of the earth crust, and human beings cannot limit the activities of the tectonic ground cracks, so that the damage zones (influence zones) of the ground cracks can be determined only by surveying and analyzing the engineering geological environment of areas and engineering fields, and the construction facilities can avoid the influence zones or the influence zones of the ground cracks as far as possible. According to the importance degree of various buildings, the avoidance distance between the building and the ground crack is regulated. For engineering facilities which are difficult to avoid, anti-cracking and anti-sinking measures are adopted to prevent the damage of ground cracks. For the ground cracks influenced by human activities, the occurrence and the development of the ground cracks are prevented by improving the human activities. The formed ground cracks can be treated in a targeted manner by adopting methods such as backfilling, tamping, pouring and the like.

The ground cracks with structural causes are usually in the form of multi-stage goose-row combination on the ground surface, and some cracks can be connected into huge cracks. A portion of the earth fracture is associated with seismic activity; the earth fractures created by a strong shock are called seismic fractures. Another type of locally developed formation fracture may be unrelated to tectonic effects, such as formation fractures created by ground subsidence caused by excess production of groundwater; the mine goaf roof fall or karst collapse and the like can also generate ground cracks and the like on the ground surface; the third kind is the West' an ground fissure, which is basically controlled by the structural fracture and is not related to the earthquake, but obviously develops the ground fissure aggravated by the excess exploitation of the underground water, and the total number of 11 ground fissures which are distributed from north east to north east in an approximately equidistant and parallel way penetrate through the urban area, not only develop in the loess layer, but also cut off the concrete building, the asphalt roadbed and the ancient city wall.
