摘要
以实际地面沉降数据为基础,分别用灰色模型、时间序列模型对实测数据进行预测,然后按照一定方法对灰色模型、时间序列模型赋予合理权值,建立了灰色-时序组合模型^([1])。预测结果表明,组合模型的预测精度更为准确、可靠,说明该组合模型具有一定的可适用性。
Respectively based on the actual ground subsidence data, using the grey model, time series models to forecatt the measured data, then according to certain method of grey model, time series model gives reasonable weights, estab-lished a gray-timeseries model [1]. The prediction results show that the prediction precision of the composite model ismore accurate and reliable, which indicates that the composite model has certain applicability.
