Common forms of uneven settlement cracks in foundations include straight splay cracks, inverted splay cracks, oblique cracks, vertical cracks, and horizontal cracks.

In areas where the rigidity of the room space is weakened, cracks are prone to appear and are concentrated. Secondly, the distribution of cracks is related to the settlement curve. When the settlement curve is slightly concave, cracks are mostly in the lower part of the house, and the width of the cracks is larger at the bottom and smaller at the top.
