摘　　要：采用封闭爆炸的方法研究了不同钢纤维含量的混凝土爆压成型的空腔大小与钢纤维分布的特征。结果表明,空腔大小与钢纤维的含量有关;钢纤维的方向发生变化,变化的幅度取决于与装药的距离及钢纤维的含量。钢纤维混凝土作为同步爆炸成型地下空间的衬砌材料是可行的。Size of cavity and steel fiber distribution characteristics of explosion forming were studied in different steel fiber content reinforced concrete with closed explosion. The results showed that the cavity size related to the steel fiber content, directions of steel fibers were changed, and the degree of their change depended on the distance of explosive and steel fiber content. Steel fiber reinforced concrete as the lining of synchronous explosion forming underground space is feasible.

关 键 词：同步爆炸成型技术 钢纤维混凝土 空腔 钢纤维分布
