Abstract
道路舗装の管理維持には,アスファルトの表面に走行する車両の車輪からどのような軸重負荷が課せられているかを把握することが重要である.しかし,静止状態で計量した軸重値は,走行速度や気象条件なんど走行条件が加味されていないため現実的な評価をするためには情報が不足しており,走行中の車両から直接動的に計量することが求められている.そこで,光ファイバブラッググレーティングを用いた圧力センサを用いてリアルタイム軸重計を構築し,これを道路に埋設し,各種気象条件下において,各種軸重の車両を用いて,各種走行速度でデーター取得実験を行ったのでその結果を報告する.
This report describes on dynamic sensing of road maintenance data by using fiber Bragg-grating(FBG). For effective maintenance of asphalt paved road, pressure load from wheels of vehicles running on the surface However, the values of wheel axial weight obtained by usual steady measurement is not enough to evaluate its practical effects because of lack of the driving condition, such as passing speed(km/h). In this report, a dynamic sensing system for the measurement of vehicle axial weight, in real time, and driving speed and passing line, in addition, by using FBG pressure gauge. The system was applied under road surface and tested under various driving conditions. In conclusion, FBG sensor works well for the dynamic measurement of road maintenance data with good response and reliability.
