【 摘 要 】

The safe transportation of liquefiable cargo is an important topic in the research on modern transportation safety of watercraft. The current study on this topic is mainly focused on the research after the liquefiable occurs. A numerical analysis model for the liquefiable of flowing particles is established using the Finn liquefiable constitutive relation, and the kinetic equation analysis module of finite difference method is adopted to analyze the liquefiable problem. The result shows that applying the Finn constitutive model to the analysis of liquefiable of flowable cargo can better predict the increase of pore water pressure and decrease of effective stress under the action of external load.
