Abstract

Abstract: In order to comprehensively understand the settlement and deformation process of subgrade, on the basis of the field monitoring data on subgrade settlement, a new scheme was designed: application of V/S analysis, M-K test and SR test to determination of the overall deformation stage and subgrade deformation tendency. The effectiveness of the scheme was demonstrated by the data on a section of Jinghu railway.

Key words: railway subgrade, rescaled variance statistic(V/S)analysis, Mann-Kendall(M-K) test, Spearman's Rho(SR) test, deformation trend judgment
