Study on the Deformation Rule of Concrete Pavement Under Explosive Loading

摘要

The finite element analysis models of air,concrete slab,soil and explosives,based on numerical calculation,are established.ALE algorithm adopted,energy releasing process of explosive material is described by high explosive combustion model and JWL state equation,and so attenuation law of soil pressure distribution and motion law of ground displacement field are received.The results would have greatly helped to reflect actual situation and to provide basis for the explosion destroy study on ground surface and safety evaluation.
