摘要
The nonlinear structure dynamic analysis code LS-DYNA is utilized to analyze the soil-spudcan interaction in three dimensions in order to predict the fixity of the spudcan sitting on the seabed. The present paper describes a practical procedure to predict the fixity of spudcan footing of jack-up rigs and summarizes some important issues which may affect the accuracy of simulation results of the soil-structure interaction, such as sand properties, the extent of soil domain and the subsidence of sand under gravitation. In addition, it is demonstrated that how to model and use the seabed sand properties in numerical models is crucial on the accuracy of the simulation results. The simulation results of soil-spudcan interactions and knowledge-sharing in relevant simulations will benefit to the design of jack-up units as well as the site specific assessment of mobile jack-up units.
