摘要
主要介绍了沪昆高速铁路杭长二分部的沉降观测,应用不同的函数模型拟合和预测观测结果,在与实际观测结果对比的基础上,分析了各种函数模型的优缺点,以提高路基沉降预测的准确性,为高速铁路的安全施工和运营提供参考。
The paper mainly introduces Hang-Chang 2nd branch settlement observation of Hu-Kun high-speed railway, and applies different multiquadric function fit model and predictive observation result. On the basis of comparing to actual observation results, it analyzes merits and defects of multiquadric function fil models in order to improve the subgrade settlement predicting accuracy. As a result, it has provided some guid- ance lot high-speed railway construction and operation safety.
