新伊高速毗邻隧道遮阳棚光环境及降碳分析
Light Environment and Carbon Reduction Analysis of Sunshade in Adjacent Tunnel of Xinyi Expressway
摘要
Abstract
In order to reduce traffic accidents caused by light intensity differences,based on the Xinyi expressway project,a combined structure of reinforced concrete and steel structure was installed in the Songjiawa-Shuigouhe adjacent tunnel connection section.The length of the sunshade was calculated based on the speed limit,DIALux simulation software was utilized to investigate two working conditions at different time,and the carbon emission factor method was used to analyze the carbon emissions under different working conditions.The results show that the length of the sunshade in the adjacent tunnel connection section is 100 m.After the installation of the sunshade,the reduction rate of road illuminance reaches 57.97%,the overall illuminance uniformity is greater than 0.4,and the error between the on-site measured value and the simulated value is within 10%,both of them meet the requirements of the relevant standard.In addition,after the installation of the sunshade,the annual carbon emissions can be reduced by 82.56 t CO2e,the carbon emissions generated during construction can be offset after 2.8 a of operation,and the construction costs will be recouped after 3.7 a.During the service life,the carbon emissions are reduced by 3 795.74 t CO2e and the costs are saved by 5.773 1 million yuan,the dual effects of emission reduction and cost savings can be achieved.关键词
