用于监测木结构应变的分布式传感光纤的安装方法
摘要：
本发明公开了一种用于监测木结构应变的分布式传感光纤的安装方法，其步骤为：制造多个光纤分布单体（14），每个光纤分布单体（14）包括前段信号传输光纤段（12）、应变监测光纤段（10）、后段信号传输光纤段（13）和两个光纤固定端；将多个光纤分布单体（14）依次串联，并在最前面一个光纤分布单体（14）的前段信号传输光纤段（12）前端和最后面的一个光纤分布单体（14）的后段信号传输光纤段（13）后端分别熔接一个光纤接头；再将串联的多个光纤分布单体（14）的基座木条（1）钉在木结构待监测的各个位置，并将上述串联的多个光纤分布单体（14）的两个光纤接头与测试仪器连接。该安装方法快速、全面、准确。
摘要（英）：

The invention discloses a method for installing distributed sensing optical fibers used for monitoring strain of a wood structure. The method includes the following steps that a plurality of optical fiber distribution monomers (14) are manufactured, wherein each optical fiber distribution monomer (14) comprises a front section signal transmission optical fiber section (12), a strain monitoring optical fiber section (10), a rear section signal transmission optical fiber section (13) and two optical fiber fixing ends; the optical fiber distribution monomers (14) are sequentially connected in series, and optical fiber connectors are welded at the front end of the front section signal transmission optical fiber section (12) of the headmost optical fiber distribution monomer (14) and the rear end of the rear section signal transmission optical fiber section (13) of the backmost optical fiber distribution monomer (14) respectively; then substrate battens (1) of the optical fiber distribution monomers (14) which are connected in series are nailed to the positions to be monitored of the wood structure, and then the two optical fiber connectors of the optical fiber distribution monomers (14) which are connected in series are connected to a test instrument. The method for installing the distributed sensing optical fibers is rapid, comprehensive and accurate.
