针对有限元等连续方法计算物体受冲击破坏的大变形问题，采用 SPH 和有限元耦合方法，对棚洞受滚石冲击破碎进行了分析，得出了滚石法向冲击棚洞结构的破碎规律，为滚石防护结构设计提供了依据。%In light of impacting damage deformation calculating problems with finite element and other continuous methods,the paper applies SPH and finite element coupling method,analyzes rolling stone impact crash for tunnel-shed,and obtains damage law of rolling stone method for im-pact tunnel-shed,which has provided some basis for rolling stone protecting structure design.
