    Abstract
  • Taking a railway tunnel entrance slope construction site as an example, the slope safety factor at different tunnel entrance elevation, different conditions (slope not excavated, excavation not loaded, loading after excavation), different conditions (natural conditions, rainstorm conditions, earthquake conditions), and different failure modes (internal sliding, multiple sliding, sliding along the contact surface) was studied. The combination of tunnel excavation and slope unloading effectively reduces the slope sliding load, optimizes the design scheme of the treatment project, ensures the safety of the project, and can provide reference for the same type of projects in route selection and slope design.
