A new method was developed to quickly and accurately assess the stability of slopes on expressways. By studying data from Fujian expressways, researchers identified 14 factors that affect slope stability. They used a statistical method called Logistic regression to create a model that can predict slope stability conditions with high accuracy. This model is reliable, easy to use, and can handle different types of data. Overall, this approach can be widely used in expressway slope engineering to assess slope stability efficiently.
