| 摘 要： | 研究目的:地铁盾构施工监测数据(特别在盾构始发段)具有数据量小,监测间隔不相等的特点,一般数据拟合与预测方法的应用受到诸多约束。研究结论:本文提出了通过预设阈值的改进非等间隔模型,并基于武汉地铁盾构二号线的积玉桥始发段的监测数据进行了拟合与预测分析。结果表明,本文方法能在数据量小,非等间隔监测数据的前提下,对地表沉降进行较好的拟合与预测,并与传统非等间隔模型的结果进行了比较。

| Abstract: | Research purposes: The monitored data on the shield construction of metro always have features of small volume and non-equal monitoring interval.It is difficult to fit or predict the data with the common methods.Research conclusions:The fitting and prediction were done for data on the Jiyuqiao start section of Line 2 of Wuhan Metro by using an advanced non-equal interval model with a certain threshold.The result showed the ground settlement data could be better fit and predicted with this method on the prem... |
