| Title of the article | Fracture mechanics application to nonlinear damage-hardening model of soil base |
| Abstract. | For the most part, resistance and displacements of the laterally loaded pile depend on the frontal soil resistance. For increasing pile resistance, the horizontal lying beams (sole), ground cap or rigid plate can be used. For this purspose, a rigid plate has been used for increased pile resistance under the changeable direction of the horizontal load and moment action. In this article on the basis of the test results of the horizontally loaded piles by nonlinear «load-displacement» curves the model of nonlinear damage-hardening soil base is proposed. In accordance with it when the load level m=Рг/Ркр (damage factor) is increasing the violation of the soil continuity is increasing in the same way. Damage factor m in the proposed subject is unlike the known model L.M. Kachanov factor affecting both damaging and hardening of soil. Thus, the proposed mathematical model of combined model of G. Rabotnov, L.M. Kachanov, the model of elastoplastic deformation of S.S. Vyalov and Bach's model with nonlinear deformation hardening. |
