摘要：假定筒仓内散体是服从Mohr Coulomb屈服准则的理想弹塑性介质 ,散体与仓壁之间的摩擦属于Coulomb摩擦接触问题。从连续介质力学的角度 ,用有限元方法研究了散体屈服对筒仓壁静态压力的影响

Abstract：In this paper，the granular media in storage is supposed to be elastic－perfectly plastic behavious material submitting to Mohr-Coulomb yield criterion，and friction effect between granular media and silo wall is supposed to be Coulomb friction contact problem．According to continuum theory，the granular media yield in silo affects the static pressure on wall of silo is studied by finite element method． 

Key words：granular media；finite element method；silo wall pressure
