Analysis on the development of chemically-improved soil in railway engineering

Abstract

PurposeExplore the development trend of chemically-improved soil in railway engineering.Design/methodology/approachIn this paper, the technical standards home and abroad were analyzed. Laboratory test, field test and monitoring were carried out.FindingsThe performance design system of the chemically-improved soil should be established.Originality/valueOn the basis of the performance design, the test methods and standards for various properties of chemically-improved soil should be established to evaluate the improvement effect and control the engineering quality.
