摘　　要：研究碳纤维混凝土处于三向受压状态时的压敏性,并通过试验完成三向受压状态及单向受压状态下循环加载,对以往学者单向受压状态下压敏性研究进行补充,并将三向受压状态下的压敏性与单向受压进行对比,发现碳纤维混凝土试块在三向受压状态下比单向受压状态下具有更为明显的电阻变化规律,且变化幅度更大,更有利地反映了荷载的变化。Study the compression sensibility of carbon fiber reinforced concrete in triaxial compression ,and do the experiments of both triaxial compression and monoaxial compression in cyclic loading, as the complementary research on compression sensitivity in monoaxial compression. Compare the compression sensibility of the carbon fiber reinforced concrete in triaxial compression and one-way compression.The results show that the change of resistance in triaxial compression is more obvious, and the variation range is larger, and can reflect the change of load better.
