基于DIALux的公路隧道洞口减光防眩措施评价

Evaluation of Light Reduction and Anti-glare Measures for Highway Tunnel Protal Based on DIALux

针对目前公路隧道洞口遮光棚的设计缺乏量化评价方法的问题,本文以苏锡常南部高速公路太湖隧道为工程实例,利用DIALux模拟太湖隧道洞口一年四季每天12个小时的日照场景,得出了遮光棚内路面照度分布。根据不同设计方案的照度水平,比对公路隧道减光防眩照度标准,优化了遮光棚的减光效果,确定了太湖隧道遮光棚的设计方案。该方法可提升隧道工程建设设计水平,为隧道洞口减光措施方案提供了行之有效的量化评价方法。

In view of the lack of quantitative evaluation method for the design of shading shed at the entrance of highway tunnel, this paper taking the Taihu tunnel of the south SuXiChang expressway as an example, simulates the sunlight scene of 12 hours a year at the entrance of the Taihu tunnel by DIALux, and obtains the illumination distribution of pavement under the shading shed. According to the illumination level of different design schemes, this paper compares the light-reducing and anti-glare illumination standard of highway tunnel, optimizes the light-reducing effect of the shading shed, and determines the design scheme of the sunshade shed of Taihu tunnel. This method can improve the level of tunnel engineering construction and design, and provide an effective quantitative evaluation method for the light reduction measures of tunnel openings.
