| 摘 要： | 对某些水库渗漏位置的检查一般采用放空水库的办法来进行,这对于严重缺水的工农业生产来说,是一种极大的浪费,采用的基于光纤光栅温度传感技术的面板坝渗漏监测系统对混凝土面板堆石坝面板渗漏能实时、在线、长期可靠监测。用于传感和信号传输的光缆可以埋置于面板底部或中性面上以及其他需要的位置,不会因机械施工而损伤,具有施工干扰小、抗电磁干扰等特点,试验表明:系统可有效检测大坝渗漏情况。

| Abstract: | The water reservoir for checking the leakage is had to empty,which is big wasteful for our industry and agriculture which have a serious shortage of water. The system of panel dam leakage monitoring based on FBG sensing technique can monitor the dam real time, on line and long-time and credible. The sensing and signaltransmission fiber cable may be placed in the bottom or mid-layer and other position,which can not be damaged in mechanical construction. Experimental tests prove that the system can efficiently inspect the dam leakage and has an advantage of anti-electromagnetism-interference. |
