Abstract:
In order to investigate the temperature field of main cable section of suspension bridge, taking Xihoumen Bridge as background, a main cable model with actual dimension section was designed and was observed for a long time. Results indicate that in sunny day, temperature difference between day and night is big. In daytime, temperature is influenced by solar radiation strength and solar altitude angle, temperature variation of each measuring point on the surface exists obvious phase difference. Temperature field of main cable section is unsymmetrical. The lag of temperature variation of inner layer to outer layer increases but temperature amplitude variation decreases in radial direction to the center point.
