Paper Title:
Research on the Safe Lighting of Minor Radius Curve Spiral Tunnels
  Abstract

Abstract: Based on the engineering background of Sichuan Ganhaizi spiral tunnel, this thesis studied the surrounding environment of portal and simulated the whole portal section, and then analyzed the effect of natural light on the portal illumination at different times. With the research on the brightness reduction and human eyes’ adaptation to it, the thesis calculated the discount rate k and obtained the requirements of vehicle speed at Ganhaizi tunnel entrance. Finally, the thesis put forward that some light reduction facilities such as vegetation outside the portal should be used, and on a clear day, from 12:00 to 15:00, the uphill tunnel portal illumination is significantly higher than other sections, thus at this time artificial lighting should be used to modulate entrance lighting.
