Type A
| Parameters |
Type A
(Effective stress analysis)
[E', n', c', f'] |
Type B
(Effective stress, Total strength)
[E', n', c=su, f] |
Type C
(Total stress analysis)
[Eu, n, c=su, f] |
| 剛度 (Stiffness) | Effective (E') | Effective (E') | Undrained (Eu) |
| 強度 (Strength) | Effective (c'=0, f) | Total (su, f=0) | Total (su, f=0) |
| 蒲松氏比 ν | 0.3 – 0.35 | 0.3 – 0.35 | 0.495 |
| 初始應力 K0 | 1 – sin(f') | 1 – sin(f') | 1 |
Undrained A：理論上 c'=0，但在數值計算中，通常會給予 1–5 kPa 的極小值以幫助數值收斂。
Undrained B and C 摩擦角 (Friction angle, f) = 0°。
