The stability of single and double side soil slopes was analyzed using a method called strength reduction and a software called ABAQUS. The study found that the stability of double side slopes is generally lower than single side slopes, but they can become similar under certain conditions. The slope angle, height, soil strength, and friction all affect the stability in a consistent and linear manner. It was also noted that different criteria for evaluating slope stability can lead to different results, suggesting the need for more complex analysis models in practical engineering.
