Abstract

The means for light environment analysis on highway tunnel portal architecture are limited. In order to solve this problem, and actively practice the development concept of "green highway" and build a tunnel portal architecture with beautiful landscape, low energy consumption, and safe driving, the BIM technology is applied in the analysis on daylight factor and glare of tunnel portal light environment. Then a simulated analysis method of tunnel portal building light environment based on BIM technology is put forward, and it is verified by field test. From the aspects of tunnel operation safety and energy saving, the light environment operation characteristics for portal tunnels with different structural types are also analyzed, and the hollowcutbamboo portal structural type is creatively put forward and is successfully applied in Yongfutun tunnel. The engineering practice shows that the portal type recommended has remarkable economic and social benefits.

Key words： BIM; highway tunnel; tunnel portal architecture; hollow-cut-bamboo portal; light environment
