| 摘 要： | 临汾市区是继西安、大同等地区之后又一地裂缝灾害比较严重的地区, 已经严重影响着临汾市经济的可持续性发展。经研究表明, 地下水超采为影响该区地裂缝灾害的第二大因子, 它是通过地面沉降来促使地裂缝的形成和发展。本文通过对临汾市区地面沉降进行数值模拟, 总结出了地面沉降的变化规律。分析认为, 地裂缝灾害的易出现部位为沉降梯度陡变带, 即沉降梯度最大处。

| Abstract: | Linfen City is one of the most serious ground fissure hazard areas in addition to Xian and Datong. It has constricts the sustainable economic development severely. Some researches demonstrate that groundwater over pumping is the second factor influencing the ground fissure hazards and assisting ground fissure formation and development via subsidence. By numerical simulation, we found the subsidence regularity, and the position prone to ground fissures is probable the seep gradient zone of subsidence. Finally, the spatio temporal regularity of subsidence and ground fissure was analyzed. |
