摘要
采用数值模拟的方法,计算比较不同形式和厚度横隔板的纵向箱型梁在给定爆炸载荷下的结构响应,结果表明横隔板的厚度和结构形式对箱型梁的抗爆防护能力有较明显的影响,在给定的爆炸载荷条件下,适当增加横隔板厚度可以提高箱型梁抗侧向变形能力和对内部管线的保护能力。
Using numerical simulation method , the structural response was calculated of the longitudinal box of different types and thickness diaphragm plate in a given explosive load , the results showed that thickness and structure types of diaphragm plate have obvious influence on the blast protection ability of box girder .In the given explosive load , the appropriate increase of diaphragm plate thickness can improve the resistance to lateral deformation capacity of box girder and the protection ability of the internal pipeline .
