| 摘 要： | 采用一级气炮设备对C100钢纤维混凝土进行了高应变率冲击压缩实验,对一维应变状态下的混凝土冲击特性进行了分析.试验中采用锰铜压力计测量得到了混凝土中不同拉格朗日位置处的压力波形,利用拉格朗日分析得到了应力应变曲线,冲击波峰值随传播距离而衰减,在钢纤维混凝土中衰减较慢.分析探讨了钢纤维对混凝土的增强作用.

| Abstract: | The shock properties of C100 concrete are investigated by gas gun planar impact technique. The manganin pressure gauge is used to measure the pressure-time curves of the samples. The physical quantities are all obtained by the Lagrange method. Moreover, it is observed from the measured pressure-time curves that the decay factor is smaller in the steel reinforced high strength concrete. The dynamic response is analyzed. |
