摘要

应变数据的温度补偿一直是光纤应变传感技术（如BOTDR）应用于实际工程的主要障碍

虽然目前有了不少理论方法试图解决这个问题

但实际运用起来却效果不佳。本文通过对云南白泥井3号隧道光纤应变监测项目的实例分析

提出了一种新的BOTDR温度补偿方法。应用该方法对白泥井3号隧道进行的温度场分析表明

隧道内空气温度场的温度变化明显要大于隧道结构温度场

而在总体的温度变化趋势上

它们都同当地的气候条件保持一致。

Abstract

The temperature compensation of emergence data has always been a primary impediment to the application of the Fibre Emergence Sensing Technology

for instance

BOTDR

to projects in practice.Although there have emerged quite a few theories in the hope of solving this problem

they are all deficient in real effects.This article provides a new method of BOTDR temperature compensation through the example analysis of the Fibre Emergence Inspection Project in the 3# tunnel of Bainijing

Yunnan.By using this method to analyze the temperature field in the tunnel

it shows that the temperature change of the temperature field in the tunnel is obviously greater than that in tunnel structure.However

in the general trend of the temperature change

they all maintain consistent with the local climate.
