Abstract

For the deformation and instability of highway embankment on sloping foundation, this paper adopts finite element software PLAXIS to numerically simulate the deformation pattern and safety stability of embankment on sloping foundation under the working conditions of construction period, operation period and rainfall period. The analysis results show that: during the construction period, the deformation sensitive points of the embankment are mainly distributed in the top of the outer slope of each layer of the embankment filling layer; during the operation period, the decay of the strength of the embankment soil body will trigger the arc sliding damage, and the deformation sensitive points are located in the top of the slope tensile cracking area and the foot of the slope at the sliding shear exit; during the rainfall period, the rainwater will infiltrate to a certain depth to produce local landslides, and the deformation sensitive points are located at the top of the embankment outer slope. Finally, the relationship curve between the displacement of deformation-sensitive points and the stability of the embankment is established by simulating the deformation damage process of the embankment, and then the safety and stability of the embankment is evaluated.
