기후조건과 레일온도

초록

In order to secure stability of continuous welded rail and improve efficiency of maintenance work, it is very important that grasp the change trend of rail temperature during 4 seasons. To analyze the change trend of rail temperature according to climatic condition, ambient temperature, humidity, solar radiation, and wind velocity are measured in a outdoor experimental place. This research propose the correlation between climatic condition and rail temperature by season through analysis of results of measurements.
