Abstract

The main purpose of this paper was to investigate the influence of soil resistance parameters, the resilient modulus (MR), CBR, and other effective factors on the slope stability coefficient of the road embankment using Plaxis software. Hence, A 4-lane freeway was designed using the AASHTO design method to examine the stability coefficient of the road embankment. Embankment modeling was carried out with three slopes (1:3, 1:4, and 1:6) using the finite element method in To this end, soil resistance parameters such as (CBR, cohesion, internal friction angle, poisson’s ratio and so on) were used to analyze the stability of the embankment. The results showed that the higher the CBR of the subgrade, the higher the safety factor of the embankment, and the lower the CBR of the subgrade, the lower the embankment safety factor.
