为了预测沉降的程度，利用1960 ~ 1993年天津地区34年地下水开采、地下水位和沉降程度的实际资料中的25年，利用Stat.软件SPSS10.0建立了开采-沉降和地下水位-沉降的线性方程。在对线性方程进行校核后，利用后9年的实测数据对该模型的沉降程度进行了预测。据此，提出了一种基于地下水开采的线性沉降预测模型。
To predict to what extent the subsidence goes, 25 of 34 years of factual data about groundwater exploiting, water table and subsidence extent from 1960 to1993 in the Tianjin proper are used to set up linear equations on exploitation-subsidence and water table- subsidence by Stat. Software SPSS10.0. After checkout of the linear equation, later 9 years of data are used to predict the extent of subsidence by the model. Thus, a linear model has been put forward to predict the subsidence according to groundwater exploitation.
