摘要
分析了华北平原地区因超量开采深层地下水，引起土层压缩及地面沉降的成因和规律；依据深层地下水非稳定流抽水原理和地层渗透固结理论，计算地下水位下降后形成的深层粘性土层的压缩量和地面沉降量．
According to the pumping principle of the unsteady flow of deep ground water and the theory of the permeability consolidation of soil layers. only analyses the causes and laws of soil layer compression and settlement caused by over-tapping the deep ground water in the North China Plain, but also calculates the compression of the deep clayish layer and the ground settlement after the drop of the ground water table.
