摘　　要：文章结合隧道施工的实际情况,提出针对性的隧道通风优化措施,并通过现场实测数据对其效果进行验证。实测结果显示,优化设计后的通风系统在某高速公路隧道施工期间效果显著,确保了空气质量达标,二氧化碳浓度降至0.06%,粉尘浓度减少了62.5%,提高了施工环境的安全性和舒适性;通过调整风管布置、增加风机配置和引入湿度调节系统,有效解决了现有通风方案中存在的湿度过高的问题,提高了系统的整体性能,研究成果可为类似隧道施工提供参考和指导。Based on the actual conditions of tunnel construction,this paper puts forward targeted optimization measures of tunnel ventilation,and verifies the effects through field measured data.The measurement results show that the optimized ventilation system has a significant effect during the construction of an expressway tunnel,which ensures that the air quality meets the standard,the carbon dioxide concentration is reduced to 0.06%,the dust concentration is reduced by 62.5%,and the safety and comfort of the construction environment are improved;by adjusting the air duct layout,increasing the fan configuration and introducing the humidity control system,the problem of excessive humidity in the existing ventilation scheme is effectively solved,and the overall performance of the system is improved.The research results can provide reference and guidance for similar tunnel construction.
