地面沉降与地下水水位变化不同步,且地面下沉受自身影响较大,建立滞后作用下地面沉降预测模型,以某地区地面沉降为例进行模拟试验,并探讨模型拟合效果与预测精度。结果表明,自回归分布滞后模型的拟合效果较好,预测精度较高,可以用到地面沉降量计算中。
地麵沉降與地下水水位變化不同步,且地麵下沉受自身影響較大,建立滯後作用下地麵沉降預測模型,以某地區地麵沉降為例進行模擬試驗,併探討模型擬閤效果與預測精度。結果錶明,自迴歸分佈滯後模型的擬閤效果較好,預測精度較高,可以用到地麵沉降量計算中。

Ground subsidence is not synchronous compared with the fluctuation of groundwater table ,and greatly impacted by itself . An autoregressive distributed lag model is established to predict ground settlement .T he fitting effect and prediction accuracy of the model are discussed based on a certain area of ground settlement .The results show that the autoregressive distributed lag model is well fitted with higher prediction accuracy ,so the model can be applied to the field of the land subsidence .
