摘　　要：根据实测数据分析抽取地下水不仅引起地表下沉 ,而且还引起水平移动 ,且在一定区域内水平移动比下沉更显著 ,进一步指出水平移动系数已不再是一个常量 ,而是与抽水井降深和观测点距抽水井距离有关的变量。本文所建立的计算模型 ,可以预测抽取地下水引起地表下沉和水平移动与变形值 。Drawing groundwater can cause not only subsidence, but also horizontal displacement based on the analysis to observing data, and the horizontal displacement is more obvious than subsidence in the specific region. The paper points out further that the horizontal displacement coefficient is variable which is relation to the value of water's decline and the distance from the observe point to pumping well. The model that the paper established can predict the subsidence, horizontal displacement and distortion caused by drawing groundwater, and can give the proof to predict the influence extent on not mining subsidence.
