摘要：According to the lighting energy-saving standards of plateau tunnels, the optimal lighting parameters in the middle segment of the highway tunnel is investigated under the conditions of plateau environment. With the minimum total power consumption as the target and the tunnel driving safety as the basic conditions, this article sets up parameter models of centerline layout, centerline sideways, symmetrical sides, and staggered sides in total 4 styles of distribution lights in tunnel interior zone. It is divided into different groups, each of which simulates 15 sets of parameters with different lamp spacing and compares the average luminance of different lamp forms and spacing conditions. The results show that: under the same spacing, the luminance of staggered sides arrangement is the highest, and the effect of centerline sideways is the worst. With the increase of the altitude, the safe lamp spacing decreases. The spacing of distribution lights in the middle section of the tunnel with the altitude of 2000m, 3000m, 4000m and 5000m is 47.5m, 42.5m, 37.5m and 35m respectively.
