Landslide cracks are a type of ground cracks:
The rock and soil on the slope have a tendency to slide under the action of gravity. When the anti-sliding force is reduced due to natural or man-made factors and the sliding force is greater than the anti-sliding force, the slope will become unstable and ground cracks will form between the sliding body and the immobile body.
Classification: According to their shape, cracks are divided into surface, depth (depth up to 1/2), through, wide at the top and narrow at the bottom, wide at the bottom and narrow at the top, date pit-shaped, outer Wide inside, narrow inside, etc.
Settlement cracks are cracks in masonry structure buildings caused by uneven settlement, usually in the form of figure-eight, inverted figure-eight and one-sided cracks

Characteristics of settlement cracks: The settlement of a building with a figure-eight crack is large in the middle and small on both sides;
The settlement of a building with an inverted figure-eight crack is small in the middle and large on both sides;
The settlement of a building with an inverted crack gradually increases along the inclined direction of the crack.
