Slope Stability Parameters: Taylor#45
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 | depth factor D (dimensionless) | friction angle deg (deg) | method | notes | slope angle deg (deg) | stability number Ns (dimensionless) |
|---|---|---|---|---|---|---|---|
| Taylor#45 | phi0#D1#ru#kh | 1 | 0 | Taylor | phi=0 | 45 | 0.224 |
| Taylor#45 | phi0#D1.25#ru#kh | 1.25 | 0 | Taylor | phi=0; D=1.25 same as D=1.0 at steeper slopes | 45 | 0.225 |
| Taylor#45 | phi0#D1.5#ru#kh | 1.5 | 0 | Taylor | phi=0; D=1.5 converges to D=1.0 at steep slopes | 45 | 0.225 |
