                  摘要: 为评估柱形装药接触爆炸对钢纤维钢筋混凝土(steel fiber reinforced concrete, SFRC)结构的成坑效应,采用
               光滑粒子伽辽金与结构化任意拉格朗日-欧拉流固耦合算法建立了                        SFRC  靶体数值模型,研究了不同装药量          Q  和长径
               比  l/d  联合作用下  SFRC  靶体的破坏模式和损伤程度,基于接触爆炸理论与量纲分析,引入爆坑系数                        K 1 与 K 2 构建了爆
               坑直径  D  与深度  H  随有效装药量    Q e 变化的预测模型。结果表明:不同装药量和长径比联合作用下,SFRC                    靶体主要呈
               爆炸成坑破坏。不同装药量情况下,当             l/d  由  1  增大至  5  时,爆坑直径  D  与深度  H  均减小了约  50%。在  Q e 小于  16 kg  范

               确的计算,为    SFRC  结构的抗爆设计提供理论依据。

               Abstract:  To evaluate the crater damage effect of cylinder charge contact explosion on steel fiber reinforced concrete (SFRC)
               structures,  a  numerical  model  of  an  SFRC  target  was  developed  by  the  using  the  smooth  particle  Galerkin  method  and  a
               structured arbitrary Lagrange-Euler (SPG-S-ALE) fluid-structure interaction algorithm. The failure modes and damage of the
               SFRC target under different charge mass Q and length-to-diameter ratios l/d were investigated. Based on contact explosion
               theory and dimensional analysis, cratering coefficients K  and K  were introduced to develop predictive models for the crater

               charge mass and length-to-to-diameter ratio, the primary failure mode of the SFRC targets is cratering damage. Under constant

               charge  mass  conditions,  as  the  l/d  ratio  increases  from  1  to  5,  both  the  crater  diameter  D  and  depth  H  decrease  by
