摘　　要：通过对C30钢筋混凝土板与体积含量为1％和2％的2种C30钢纤维钢筋混凝土板TNT接触爆炸对比试验，考察了3种试验构件迎爆面和背爆面宏观破坏现象，分析了钢纤维掺量对C30钢纤维钢筋混凝土板迎爆面和背爆面局部破坏影响，得出了增加钢纤维掺量具有明显改善RC板抗震塌性能的结论，指出了不同钢纤维掺量时RC板具有不同局部震塌破坏特征，为钢筋混凝土抗爆设计提供参考。Macroscopic damage phenomena on the front and back surfaces of three kinds of test specimen are researched by contact explosion through coutrast tests on C30 RC plates and C30 steel fiber reinforced concrete plates with 1% and 2% steel fiber content respectively. The effects of steel fiber content on the damage characteris- tics of the front surface and back surface of C30 steel fiber reinforced concrete plates are analyzed. The test results show that the addition of steel fiber in concrete could enhance the capability of RC plates for resisting spalling dam- age. The RC plates with different steel content have different local spalling damage characters. Test data from the experiment are important reference to explosion resistance design of steel fiber reinforced concrete structures.
