在提出客运专线路基沉降预测重要性的基础上,以灰色预测模型GM(1,1)和双曲线模型,对路基沉降变形观测数据进行了分析预测,并结合实例,编写matlab程序,对这两种预测结果做了对比分析。结果分析显示:灰色预测模型GM(1,1)比双曲线模型在客运专线路基沉降预测具有更高的精度,效果更佳。
On the basis of the importance of subsidence prediction of passenger dedicated railway line, this paper analyzes and predicts the subsidence deformation observation data with gray prediction model GM (1,1) and hyperbola model, and compiles the matlab program with these two The forecast results have done a comparative analysis. The results show that the gray prediction model GM (1,1) has better accuracy and better effect than the hyperbolic model in the subsidence prediction of passenger dedicated railway line.
