用分离式钢筋混凝土模型建模,利用ANSYS/LS-DYNA软件对高强钢筋混凝土板抗接触爆炸破坏形态进行数值模拟,其中钢筋采用随动硬化模型,混凝土采用HJC模型。结果表明:高强钢筋及其配筋率、钢筋布置方式对爆炸成坑的尺寸和震塌破坏程度有一定的影响,配筋率越大,钢筋间距越小,钢筋强度越高,震塌破坏的面积越小。通过与试验结果对比,数值分析与试验结果比较吻合。 The model was built by using separate reinforced concrete model. The anti-contact explosive failure mode of high-strength reinforced concrete slab was numerically simulated by ANSYS / LS-DYNA software. The model of follow-up hardening was adopted for reinforced concrete and HJC model for concrete. The results show that the high strength steel bars, the reinforcement ratio and the arrangement of steel bars have a certain impact on the size of the explosion pits and the degree of collapse and collapse. The larger the reinforcement ratio, the smaller the steel bar spacing, the higher the strength of steel bars, The smaller the area. By comparing with the test results, the numerical analysis is in good agreement with the test results.
