Assembly Blast Walls and Concrete Blast Walls Comparative Analysis of Protective Effectiveness
To reduce the terrorist bombings and the occasional blast damage to people and buildings, a style of steel-sandstone-steel assembly blast walls was designed. To analysis the protective effectiveness of blast walls against the blast wave, The concept of overpressure Protective effects coefficient was proposed. The computational model of assembly blast walls was Established and three-dimensional numerical simulation for the assembly blast walls by using ALE and JWL state equation for the product of explosive detonation was Carried out. Empirical formula calculation results and the test results in the Ref are in good agreement. Using this model the protective effects for blast walls of steel plate with sand, blast walls of steel plate with concrete, concrete blast walls and was studied by 3D numerical simulation. The analyses indicate that protective effectiveness of steel-sandstone-steel blast walls was better than the concrete blast walls and the steel-concrete-steel blast walls.
