为积极践行“绿色公路”发展理念，打造景观美、能耗低、行车安全的隧道洞门建筑，解决当前公路隧道洞门建筑光环境分析手段有限的难题，首次将BIM技术应用于隧道洞口的日光因子分析和眩光分析，提出一种基于BIM技术的隧道洞门建筑光环境仿真模拟和分析的方法，并得到现场试验验证。从隧道运营安全和节能角度对不同结构型式洞门隧道光环境运行特点进行分析，创新性提出了镂空削竹式洞门结构型式，并成功应用于永福屯隧道。工程实践表明，该洞门型式的经济效益和社会效益显著，推广应用前景广阔。
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 hollowcutbamboo 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.
