| 摘 要： | 传统的灰色模型多适用于等间距序列监测数据的模拟预测,而实际上由于各种原因往往使所获得的监测数据是不等时距的。研究了基于不等时距灰色预测方法的深基坑变形预测模型,应用深基坑工程变形的实际监测资料,对其预测精度及可行性进行了充分的分析比较与论证。结果表明,不等时距灰色模型预测深基坑变形的精度及可信度较高。

| Abstract: | Traditional Grey Model is usually used for simulation and prediction of monitoring data series with equal interval. But actually, the monitoring data are often collected with unequal time interval as the observational conditions are limited. The model of deformation predication on deep construction pit is studied on basis of unequal time interval Grey Model and the accuracy and feasibility are also analyzed by applying practical monitoring data. It is demonstrated that the accuracy and reliability of unequal time interval Grey Model is higher than traditional models. |
