基于主成份分析法的高速铁路膨胀土判别研究
Discriminant analysis of high speed railway expansive soil based on principal component analysis
摘要
Abstract
This article mainly talks about expansive mudstone of high speed railway foundation in a Railway, and combines with the characteristic of its strict requirements about displacement. There are 4 indexes which were selected as model factors to establish mathematical model of discrimination of high speed railway through principal component analysis and the model is validated by the expansion force.The results show that the model can accurately distinguish the expansive soil in the foundation and predict the swelling properties of mudstone.关键词
