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

Abstract

Purpose – Explore the development trend of chemically-improved soil in railway engineering. Design/methodology/approach – In this paper, the technical standards home and abroad were analyzed. Laboratory test, field test and monitoring were carried out. Findings – The performance design system of the chemically-improved soil should be established. Originality/value – On 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.
