Experimental Research on Improvement of Railway Subgrade Loess Fills Using Lime in Northwest China

Abstract:

Theexperimental research on the double-track railway Lanzhou-Wuwei Railway (a partof Lanzhou-Xinjiang Railway) subgrade loess fills improved with lime revealsthe stiffness mechanism as well as the connection between stress and strainafter the lime treatment of loess. It also analyzes the influential propensityseveral factors have to the lime-improved-loess stiffness and comes up withinfluential patterns these factors have to the stiffness. The experimental resultplays an instructive role in the application of lime-improved-loess in sitespecific projects.
