光纤测量技术在混凝土面板破损检测中的运用

Application of the Optical Fiber Measurement Technique in Damage Detection of Concrete Dam Face

运用光纤测距技术,将光纤埋设在大坝混凝土面板内部,定期测量光纤长度,当面板发生破损时,光纤在破损处产生新的断点,通过测量断点距离的变化,则可以及时发现破损现象,并计算出破损位置。

The application of a distance measurement technique using optical fiber in damage detection of concrete dam face is introduced. The optical fiber is embedded in the concrete face of the dam. And the length of the fiber is measured regularly. If any damage occurs in the concrete face,new breakpoints will be generated in the optical fiber in the location of the damage. Through the measurement of the distance between the breakpoints,the damage could be detected timely and the damage location could be also calculated.
