Hi everyone!
The safety factor is a factor for checking the results. How much is the safety factor for different slopes based on different standards or guidelines such as UIC, British standard, and etc.? Is it different for rock slope or soil slope in different conditions such as static or dynamic conditions (ODE/MDE/MCE)? Should it be considered based on special projects like high speed railway or other projects?
Thanks in advance for sharing your experience!

Safety factors differ for soils and rocks. Also, they are different for static loading and earthquake loading conditions. Most of the times, every project has a specific requirement, based on spatial variability of rock/soil properties. I am involved in the slope stability analysis of Himalayan rock slopes for Chenab Railway Bridge project. The factors of safety under static, design basis earthquake and maximum credible earthquake set for this project are 1.5, 1.2 and 1.0 respectively. Also, it's not just the factor of safety, but the maximum allowed deformations along the slope, that govern the design most of the times.
