| 中文摘要 | qinghai-tibet railway is the longest and highest plateau railway in the world. a long term monitoring system of the stability of the subgrade in the permafrost regions should be put forward immediately to prevent damage to the railway. as it's very difficult to set up the long-distance automatic monitoring system which contains a lot of measure points along the 550 kilometers railway in the permafrost area, we present a subgrade temperature monitor system based on fiber bragg grating (fbg). in this paper the principles of the fbg was presented, and the feasibility of the fbg sensors in the permafrost area of qinghai-tibet plateau was analysized. we embedded fifteen fbg temperature sensors and thermal resistance temperature sensors. a contrast experiment is made while the two kinds of sensors are arranged in the same position. the result of the experiment shows that the accuracy of the fbg temperature sensors is less than 0.1 degrees c. and the fbg sensors can do well in the measurement of pattern which the temperature varies with the depth of the permafrost soil. the result also shows the stability of the fbg sensors in the bad environmental condition of qinghai-tibet plateau, which proves the feasibility of the application of fbg sensors and our monitoring system on the qinghai-tibet railway. |
