摘要
采用钢纤维RPC混凝土制作7个遮弹板,运用几何相似的方法确定炸药量,进行了2组接触爆炸模型试验。对试验现象进行了描述,通过数值模拟,结果与宏观试验的对比分析符合较好,验证了计算方法和模型构建的正确性。由爆炸漏斗坑尺寸计算得到压缩破坏系数与理论计算得到的进行相比,二者差别不大,从而说明得到的压缩破坏系数是准确的,可以应用到实际工程中。
Two sets of model experiments of contact explosion were performed on the basis of fabricating seven steel-fiber RPC shelter plates and the quantity of explosive was gained through method of geometric similarity. The experimental macroscopic damage is described, the numerical results are compared with observations in experimental results, and the good agreement between them shows that the numerical method and models used are reliable. Compared the explosive compression coefficient computed by infundibular crater size with that of theory deducing, it is found that the distinction is small and the compression coefficient can be applied to practical project owing to its reraclousness.
