| Abstract: | In order to accurately define and understand the Bishop's stress, the definition framework of generalized effective stress is put forward by considering the shortcomings of constitutive model of unsaturated soil. And then it compares with the traditional definition framework of the Bishop's stress. Finally, the matric suction, cementation action and hardening process are discussed. |
| Keywords: | generalized effective stress Bishop's stress matric suction constitutive relations hardening parameter |
