Slope Stability Parameters: Bishop_simplified#40
Slope stability parameters — Taylor stability numbers (Ns) for c-phi and phi=0 soils with depth factors, infinite slope factor of safety (dry and saturated), and Bishop simplified method FS values with pore pressure ratio and seismic coefficient
| method slope | phi D key | cohesion ratio c over gamma H (dimensionless) | depth factor D (dimensionless) | factor of safety (dimensionless) | friction angle deg (deg) | method | notes | pore pressure ratio ru (dimensionless) | seismic coefficient kh (dimensionless) | slope angle deg (deg) |
|---|---|---|---|---|---|---|---|---|---|---|
| Bishop_simplified#40 | phi20#D1#ru0#kh0 | 0.08 | 1 | 1.25 | 20 | Bishop_simplified | phi=20 deg; steep embankment slope; FS=1.25 minimum for end-of-construction per USACE | 0 | 0 | 40 |
