依据合武（合肥-武汉）Ⅰ标段设置路基沉降观测的数据，提出了对高速铁路路基施工进行动态控制方程的公式形式和工后路基沉降预测的依据与具体实现，并结合典型观测数据进行分析和路基施工控制，确保路基质量、沉降、工期要求。

In this paper, the author proposed the formula of dynamic construction control and settlement forecast about roadbed of high-speed railway according to the observation data of Hefei-Wuhan Express Passenger Line I Bid Package,combining the classic observation data to analyze and control roadbed construction for ensuring that the roadbed quality,settlement and the timelimit can meet the requirement. The method of this paper can be referred in the similar roadbed construction.
