摘 要:在概述济宁市水文地质条件的基础上,分析了济宁市区地下水超量开采引起地下水环境的变化,使地下水水位不断下降,形成地下水降落漏斗,地下岩层在上覆土层压力的作用下,压缩变形,而产生地面沉降。初步分析了地下水位变幅与地面沉降量间的关系,并预测了未来几年里的沉降量,分析表明沉降量仍在不断地增大。为此提出了相应的防治措施和对策, 以避免进一步恶化济宁市环境地质问题。On the basis of hydro - geological conditions of Jining city, some factors of caused land subsidence were aralyzed. The groundwater is overdrawn in urban area of Jining city, which caused the variation of groundwater environment and makes groundwater table drawdown continuously and formed cone depression of groundwater table. Under the pressure of the above earth, the stratums are compressed and deformation, land subsidence appears. The correlafivity of land subsidence and groundwater table changes were established. The amount of land subsidence is forecasted, the result shows that the amount is increasing in future years. In this paper the author puts forward the corresponding control countermeasures to limit its expansion.
