英文摘要	In order to study treatment measures for the land subsidence caused by deep groundwater overexploitation, we conducted soil compression and rebound tests to analyze the unloading and rebound regularity of deep soil on the fringes of three typical land subsidence regions in North China. Using fuzzy mathematics, we specifically explored the main factors influencing the soil mass unloading resiliency. The results indicated that the ratio between the unloading resilience volume and the loading deformation volume of soil mass in the study areas (referred to as the resilience capacity of soil mass) is between 1.6 and 37.6 %, with an average of 14.7 %. In other words, only about 14.7 % of the land subsidence deformation in the study areas can be restored. The soil masses with different properties in North China all possess elastoplasticity and the resilience capacities of soil can vary from area to area. The sandy soil is not completely elastic but has a certain degree of plasticity; the resilience capacity of soil mass is not a constant, but rather, a variable that changes with the rebound stress value. When the rebounding stress value is determined, the resilience capacity under a smaller unloading stress is larger than that under a larger unloading stress, which demonstrates that earlier land subsidence treatment can result in better effects. Meanwhile, the resilience capacity of soil mass is also enhanced with the increase of rebounding stress, indicating that the closer to the original groundwater level the restored groundwater is, the better the resilience capacity will be. After repeated loading and unloading tests have been conducted under the same stress, the resilience capacity of soil mass will, in most cases, increase to a certain extent. These results can be quite conducive to the treatment of deep groundwater exploitation-induced disasters such as land subsidence.
