改进灰色模型高铁隧道路基沉降分析与预测
Settle ment analysis and predictation of high-speed rail tunnel subgrade based on the i mproved Gray model
摘要
Abstract
In view of the certain limitations of the grey model in the settlement prediction,this article made the Markov prediction on the basis of the grey predictation.The Markov state transition Matrix was used to improve the grey system model,and consequently,the defects of low accuracy for the stochastic voluctility data sequence was compensated.The article analyzed engineering examples in a high-speed rail tunnel and subgrade settlement monitoring data,it is concluded that the model still has better fitting and forecast result with strong deformation curve fluctuations,and thus improves the prediction accuracy.关键词
