摘要
地面沉降的准确预测对减灾防灾和指导地区工程规划和建设意义重大。使用地区地面沉降观测数据,将灰色理论模型与时间序列分析相结合,构建组合模型。该组合模型既反映地面沉降与其影响因素之间的灰色关系,又考虑地面沉降观测数据的随机性,有利于对地区地面沉降做出科学合理的预测。
The accurate prediction of ground subsidence is significant to disaster reduction and prevention, as well as construc- tion planning and building. Regional ground subsidence observation data are used to make a composite model combining the grey theory and the time series analysis. The model reflects the gray relations between ground subsidence and its influencing factors, and also considers the randomness of observations, thus conducive to make scientific and rational prediction.
