Problems solved by technology
Compared with other outdoor lighting, highway tunnels have a special semi-enclosed space structure. Due to the large brightness difference between the inside and outside of the tunnel entrance and exit, when vehicles pass through the highway tunnel quickly, "black holes", "white holes", "adaptive lag" and "visual shock" are likely to occur. and other phenomena, resulting in traffic safety hazards

Embodiment Construction
[0021] Below in conjunction with accompanying drawing, the present invention is described in further detail, as shown in the figure:
[0022] A tunnel linear structure optimization method based on the equivalent lighting concept provided by the present invention includes a tunnel body, the side walls of the entrance end and the exit end of the tunnel body extend to the outside of the tunnel with a curvature P to form an extension section 1, and the projection of the extension section are the same length;
[0023] The top of the exit section and the entrance section of the tunnel is provided with a lighting shaft 2, and the lighting shaft 2 located at the exit section is set at 1 / 2 of the distance between the exit section and the lighting lamp 3 closest to the exit, and is located at the entrance section. The lighting shaft 2 in the entrance section is set at 1 / 2 of the distance between the entrance section and the lighting lamp closest to the entrance, and the lighting shaft 2...

The invention provides a tunnel linear structure optimization method based on an equivalent lighting concept, comprising a tunnel body, wherein the side walls of an inlet end and an outlet end of thetunnel body extend outward to form an extension section with curvature P; A lighting shaft is arrange at that top of the outlet section and the inlet section of the tunnel, the lighting shaft locatedat the outlet section is arranged at 1 / 2 of the distance between the lighting lamp nearest to the outlet section and the outlet section, The daylighting shaft located at the inlet section is arrangedat 1 / 2 of the distance between the lighting lamp nearest to the inlet section and the inlet section, and the daylighting shaft located at the outlet section and the inlet section is located on the longitudinal centerline at the top of the tunnel. Under the premise of ensuring the safe and comfortable lighting operation environment of the tunnel, the supplementary lighting by using solar energy after reducing the lighting system load can still achieve the original lighting design standard or meet the lighting quantity necessary for driving safety, thereby realizing the purposes of energy savingand emission reduction and tunnel operation cost reduction.
Description
technical field [0001] The invention relates to a tunnel structure, in particular to a tunnel linear structure optimization method based on an equivalent lighting concept. Background technique [0002] At present, the scale and quantity of tunnel lighting facilities are getting larger and larger, which will inevitably lead to a substantial increase in tunnel lighting power. On the premise of ensuring a safe and comfortable lighting operation environment in the tunnel, how to achieve the original lighting design standards or meet the lighting quantity necessary for driving safety through certain technical means after reducing the load of the lighting system has become an important goal for realizing energy saving and reduction. The research object of rowing and reducing the operating cost of the tunnel. Compared with other outdoor lighting, highway tunnels have a special semi-enclosed space structure. Due to the large brightness difference between the inside and outside of t...
