分析电力铁塔的塔身主材受地震、强风荷载、线路覆冰等恶劣自然因素影响而导致变形损坏之外，受到气温变化带来的热胀冷缩影响而导致受力增加的情况，介绍采用光纤 Bragg光栅（ FBG）应变传感器对塔身主材形变进行多点在线监测的方法。
分析電力鐵塔的塔身主材受地震、彊風荷載、線路覆冰等噁劣自然因素影響而導緻變形損壞之外，受到氣溫變化帶來的熱脹冷縮影響而導緻受力增加的情況，介紹採用光纖 Bragg光柵（ FBG）應變傳感器對塔身主材形變進行多點在線鑑測的方法。

The principal material of the power tower’ s body is affected by the temperature in addition to the bad natural factors , such as earthquake, strong wind and line cladding ice which lead to deformation and damage.The influence of the temperature’ s heat bilges cold shrink will cause the stress increased significantly.The tower body principal material has been online and multipoint monitored by four FBG strain sensors which are fixed axially on the conplane tower waist.The FBG will turn up centre wavelength’ s shifting when the tower body principal material is engendered bending by the temperature’ s change.
