  • To improve the slope stability of the expanding soil and improve the mechanical properties of the expanding soil, the polypropylene fiber was used to modify the expanded soil, and the shear strength change law of the slope of the modified expansion soil with different confining pressure and different polypropylene fiber dosage was calculated through the straight shear test, and then the slope of the expanded soil with different polypropylene fiber content was analyzed based on Geostudio software using the limit equilibrium method. It is found that the polypropylene fiber content can effectively improve the shear strength of the slope of the expanded soil within a certain range, and the 0.14% fiber soil showed good shear resistance in the straight shear test. The analysis results of Geostudio's limit equilibrium method show that the stability coefficient of 0.14% fiber soil slope is 2.431, which is 0.591 higher than that of plain expansive soil slope. It is recommended to use 0.14% fibrous soil to strengthen the slope of expanded soil.
