| 摘 要： | 本文应用灰色系统理论的关联度分析法,分析了上海市地面沉降在时间、空间上的变化特征,进而以市区和近郊区典型地段的地面沉降监测资料为基础,建立了灰色预测模型,并在某些假定前提下预测了上海市地面最终沉降量及“沉降寿命”。

| Abstract: | This paper describes the characteristics of variation of Shanghai land subsidence with timeand space by correlation degree analysis basedon the grey system theory.Furthermore,GM(greymodel) is set up by l-accumulated generating operation of the data of land subsidence monito-red at typical locations in urban and suburban areas in Shanghai,and time-responsefunctionis obtained.The GM model thus obtained is accordant with land susidence variations of Sha-nghai by verifiableness.With some hypotheses,the final subsidsence and the time whenthe land will stop settling in Shanghai are predicated. |
