摘　　要：在桥梁结构中,最大应变发生在结构表面。为了对混凝土结构表面的应变变化、直至产生裂缝这一过程进行实时监测,本文选用了一种智能导电材料进行结构变形观测试验研究。试验结果表明,该智能导电材料对结构表面变形跟踪及时准确,且对混凝土裂缝的出现和扩展十分敏感,在实际的桥梁健康监测中具有广泛应用前景。In the bridge structure,maximum strain occurs on the surface of the structure.In order to monitor the strain occurred on the surface of the concrete structure in real time,a kind of intelligent conductive material in chosen to observe and study the structural deformation.The results show that the intelligent conductive material can timely and accurately track the deformation on the surface of structure,and it is very sensitive to monitor the appearance and expansion of concrete cracks.It has broad application prospects in the actual bridge health monitoring.
