摘　　要：对碳纤维混凝土 (CFRC)试件进行加载实验 ,获得了压阻性 ,并对其机理进行了探讨 ;设计并制作了CFRC配筋构件 ,获得了构件在受弯时电阻及残余电阻和荷载的变化趋势 ,以及变化应力下电阻值相对变化与荷载的对应关系 .结果表明The test of loading on specimen with CFRC indicates that CFRC owns sensitivity. The mechanism of the test is discussed. Moreover, the reinforced components of CFRC is designed and produced. Changing trend of electrical resistance and remainder resistance of component when bending and corresponding relation between relative resistance changing with various stress and load are gained. Result shows that comparison of loading and remainder resistance when crushing may observe the position of damage.
