摘要
En 中文
The traditional Coulomb friction model is commonly used to illustrate interactions at the soil-structure interface, but it assumes zero tangential resistance when the normal stress on the interface is in tension. This is not realistic for modelling the undrained behaviour of geo-structures deeply embedded in the seabed because the soil adheres to the structure due to the suction generated. This note proposes a new interface model that captures the undrained behaviour of soil at the structural interface, including the ability to maintain frictional shear stresses under tensile normal stress. Based on simple elastic-perfectly plasticity theory the constitutive behaviour of the interface and the algorithm required to numerically implement it into a finite element program are fully described. Computational cases are presented to verify the model's implementation and demonstrate how the new interface model performs for cases of undrained behaviour encountered in offshore geotechnics.
