| 摘 要： | 地面沉降是近年来我国和世界上许多城市出现的重要的地质灾害之一，济宁城区1988年发现地面沉降，并以25．2mm／a沉降速度发展。本文从新构造运动、地下水开采、第四系砂土特征等方面，分析了济宁城区地面沉降的产生原因，指出新构造运动与超量抽取地下水是造成济宁城区地面沉降主要原因；通过对地下水开采量的变化趋势，中、深层地下水的补给条件的分析，对地面沉降变化趋势作出了预测；根据济宁市地处济宁矿区的特点，提出了综合利用地下水、防治济宁城区地面沉降进一步发展的对策。

| Abstract: | The land subsidence is an important geological hazard which occured in many cities all around the world in recent years. The land subsidence in urban area of Jining was first found early in 1988 year, and it's subside speed reaches to 25.2 mm/a. The paper analyzes the formation cause of land subsidence in Neotectonic movement, groundwater exploitation, and characteristic of sand and clay in quaternary. The main reasons to forming the land subsidence in this area are Neotectonic movement and groundwater over exploitation. By analyzing the changing tendency of groundwater yield and the recharge condition of groundwater in middle-bed and deep-bed, the changing tendency of land subsidence was predicted in this paper. Taking consideration of many coal mines in Jining city, the countermeasure is put forward to utilize groundwater comprehensive and to control land subsidence development. |
