The level morphological characteristics of ground fissures are influenced by the regional stress field. The morphology of ground fissures in Songzhuang were reshaped by the concentration of tensile stress and developed by the horizontal movement of a soil mass caused by groundwater overdraft. The Gaoliying ground fissures inherit the morphological characteristics of the Huangzhuang–Gaoliying fault, with differential settlement in a small area accelerating the development of Gaoliying fissures.

This article established a groundwater–subsidence model in a typical land subsidence region and classified an early land subsidence warning zone based on the results from the model. If the pumping of groundwater from the second and fourth aquifers was reduced by 50 % and pumping from the third aquifer was reduced by 60 %, the early warning level for land subsidence would be greatly reduced and would meet the requirements for land subsidence control.
