基于压电阻抗技术,对内植单个PZT传感器的混凝土梁进行建模,模拟其在无损、发生损伤、不同损伤程度的各种工况下的损伤识别过程.随后采用分布式多个内植PZT传感器确定损伤梁中裂纹的大致位置.结果表明:运用植入式PZT传感器能有效地识别混凝土梁中损伤的发生、损伤程度和损伤位置. Based on the piezoelectric impedance technique, a concrete PZT sensor embedded in a concrete beam was modeled to simulate the damage identification process under various conditions of non-destructive, damage and different damage.Afterwards, the distributed multiple implant PZT The sensor determines the approximate location of the crack in the damaged beam.The results show that the incidence, the degree of damage and the location of the damage in the concrete beam can be effectively identified by using the implanted PZT sensor.
