| 摘 要： | 城际铁路为保证线路的高平顺性,对桥梁、路基、涵洞、隧道、过渡段等线下工程沉降量有着严格的要求,必须进行沉降预测评估。基于实测数据的沉降预测方法主要有曲线拟合法、灰色系统分析模型等,本文首先对多种预测方法进行对比分析,然后综合考虑曲线拟合法与GM(1,1)模型的优点,提出一种基于GM(1,1)模型数据的曲线拟合预测方法,并通过武咸城际铁路工程实例验证,说明该方法用于城际铁路线下工程沉降预测是可行的。

| Abstract: | Inter-city railway is strict in the settlement of bridge, roadbed, culvert and tunnel because of the railway＇ s smooth, it should proceed the sedimentation prediction. The methods of sedimentation prediction mainly include the curve-fitting method and Grey model theory. The article firstly carries on the contrast analysis of several prediction meth- ods and considers the advantages of curve-fitting method and GM （1,1）model, proposes the curve-fitting prediction method based on GM（ 1,1 ）model. Verified by Wu-Xian inter-city railway＇ s project,it is indicating that the proposed new method for inter-city railway＇ s project under Line sedimentation prediction is feasible. |
