Spudcan-Soil Interaction Analysis of a Jack-up Based on Elastic-Plastic Model

Abstract:

In order to investigate the jack-up spudcan-soil interaction behaviors, numerical simulation and design of experiments (DOE) of a jack-up were presented based on elastic-plastic foundation model, in operating and survival conditions. Spudcan load assessment indexes called RV_AB, RH_ABand RM_ABwere put forward by the authors, which were also the responses of the DOE. The results showed that, for both conditions, vertical load V on spudcan A is higher than that on spudcan B, while horizontal load H2 and moment M3 on spudcan A are lower than that on spudcan B. Yield was found on the Spudcan A-soil interface, and the plastic components in survival condition are higher than the ones in operating condition. Friction angle and unit weight are two important soil parameters that have a great effect on the spudcan-soil interaction behaviors.
