摘要
本文应用灰色等间距GM(1,1)模型对恩施州电力总调度中心大楼的沉降量进行预测,其发展系数a=-0.023>-0.3可用于中长期预测。从预测值与观测值残差的大小来看,拟合结果比较理想,说明该预测是可行的;相对累计预测、观测沉降量除两次观测外,其余均小于标准0.04mm/d,说明沉降比较稳定。
Grey non-equidistance GM （1,1） model is adopted herein to forecast settlement of Enshi General Power Distribution Center Building. The development coefficient, a=-0.023〉-0.3, can be used in medium and long-term forecast. According to the residual difference between forecasted value and observed value, relatively ideal fitting result has been obtained, which approves feasibility of the forecast; compared with accumulatively forecasted and observed settlements, excluding the two observed in July 2004, are less than standard value 0.04mm per day, and stable settlement is realized.
