基于χ2检验法的轨道交通线下工程变形分析方法研究
Research on the deformation analysis method of railway underline engineerings based on the χ2 test
摘要
Abstract
Railway underline engineerings during operation and maintenance period usually bear the influence of dynamic and static load of train operation and complex factors of monitoring environment.Thus,it is hard to ob-tain good effect when predicting this deformation trend of such characteristics by curvilinear regression fitting methods.At present,the overall convergence level and developing trend of settlement curves will be decided based on experience.Obviously,such methods are neither scientific nor precise.It is urgent to find certain scien-tific standard for these settlement points whose deforming regular can’t be predicted by curve regression methods. This paper studied the the χ2 test for settlement assessment,the results show that the χ2 test can be taken as a scientific and reasonable method of settlement analysis and judgement.关键词
