| 摘 要： | 分析了改进的等维新息灰色预测模型用于深基坑变形预测的合理性。应用深基坑实际变形监测资料,对其预测精度及可行性进行了验证。结果表明,等维新息灰色模型的预测精度较高,模型的预测结果基本上能满足要求。灰色预测模型的预测精度与监测的时间间隔是否固定、数据变化的规律性是否明显有关。当规律明显时预测精度较高,而当监测时间间隔波动大、数据有大的跳跃突变时,预测精度较低。

| Abstract: | Deformation predication of deep construction pit is studied on basis of equal dimension and new information model. The accuracy and feasibility are analyzed by applying it using practical monitoring data. Results demonstrate that equal dimension and new information model can achieve better accuracy of deformation prediction; original model can also meet the accuracy requirement; finally, the accuracy is found high correlation to the interval of monitoring time and the regularity of data variety. The accuracy is higher when there is obvious regularity of data variety and is lower when there is no-equal interval or mutation in data set. |
