| 摘 要： | 本文利用非稳定准三维水流－－一维沉降耦合数学模型，采用有限元数值解，以上海行政区为计算区域，对１９８１－１９９２年地下水采灌量、水位及土层变形量等实测资料进行数值模拟，利用１９９３－１９９８年实测资料对模型进行检验，表明所确定的数学模型是合理可信的，利用该模型计算了地下水可开采量及地下水流场和地面沉降的预报。

| Abstract: | The theory analyses the mathematical model of unstable 3-dimension waterflow - 1-dimension land subsidence coupling by using finite-element numerical value solution. The model was put up with numerical value simulating actual means of groundwater mine and irrigation since 1981 to 1992, and also checked up with means since 1993 to 1998. It has indicated that it is creditable and reason able. It can be used to forecast the groundwater flow,land subsidence and the workable reserves. |
