Creep modelling of soft soil based on the fractional flow rule: Simulation and parameter study

作者：

Highlights：

• Formulated a novel creep model for soft soil based on the fractional flow rule.

• Demonstrated the advantage and availability of suitable kernel function for the proposed model through numerical analysis.

• Proved the accuracy and efficiency of the proposed model for depicting full-stage creep behaviors of soft soil.

• Established the physical significance of model parameters which is highly related to the applied stress.
