| 摘 要： | 结构健康监测中对混凝土内应力的测量一直没有得到很好的解决。针对前期工作中提出的利用埋入式压电陶瓷进行混凝土内应力检测的方法,进一步研究了在埋入状态下,两种不同种类PZT压电陶瓷的应力及温度特性。分析了在温度实验中存在的应力-温度交叉传感现象的成因,并提出了温度补偿的方案,为今后完善应力测量方法奠定了基础。

| Abstract: | Concrete stress measuring is difficult in structure health monitoring.Based on the method for measuring concrete stress by embedded PZT ceramic in the previous work,the stress and temperature characteristics of two kinds of embedded PZT ceramic are investigated.The stress-temperature cross-sensitization is found in the experiments.A scheme of temperature compensation is proposed to reduce the measuring error caused by the cross-sensitization. |

| Keywords: | structure health monitoring concrete stress temperature PZT ceramic. |
