Abstract

Based on hydrogeological data and years of land subsidence monitoring data in Liaocheng City, a 3D fluid-solid coupling numerical model of land subsidence in Liaocheng City were established. The model restored the evolution law of land subsidence caused by water extraction in the area, predicted the development trend of subsidence. Results show that (1) land subsidence in Liaocheng mainly occurs in four areas of Linqing, Guanxian, Chiping and Dong’a, and the subsidence rate is 30-50mm/a; (2) under the scenario of maintaining the current amount of groundwater extraction, land subsidence in Liaocheng will still develop in the next ten years and will reach 321 mm by 2031; (3) under the scenario of establishing no-mining zones, the subsidence will be reduced to 256 mm by 2031. It is proposed to set up no-mining zones in the eastern and northwestern part of Liaocheng to reasonably develop and utilize groundwater resources.
