机敏土建结构中光纤传感技术的研究综述

An Overview on Fiberoptic Sensing Technology in Smart Civil Structure

讨论和分析了机敏土建结构中埋入光纤传感器，对结构内部的状态参数如应力、应变、温度等的无损检测，以及对结构整体性、安全性评估的原理和方法。同时，综述了用于机敏土建结构的光纤传感器及传感系统设计，以及该项技术的实验室研究和现场应用等情况。

The paper discuss the concept of fiberoptic smart civil structure,and analysis the principle of non destructive evaluation of civil structure with the help of embeded fiberoptic sensor in sensing the inner state and integrity of the structure.The typical experiment and development of fiberoptic sensing system in the health monitoring of dam,highway,bridge and buildings are overriewed.
