Effect of different replacement depth on slope stability of roadbed

Abstract

Combined with the engineering example of Sanyangchuan tunnel and lead project in Tianshui City, firstly, the cement improved soil and lime improved soil with better mechanical properties were selected by experiment. Secondly, based on Geostudio software, a numerical calculation model is established to analyze the influence of different replacement materials and different replacement depths on the stability of the roadbed slope for different replacement ranges.
