Abstract

The amount of ventilation required in making the tunnel ventilation plan is an important factor for determining the capacity of the ventilation system. The amount of pollutant emission for each type of vehicle (basic emission amount for the design of ventilation volume) for estimating the required ventilation amount is based on the 'Standard for Allowing the Emission for the car manufacturing', proposed by Ministry of Environment. However, in 2013, the Ministry of Environment announced the 'Regulations on the calculation method of total emissions from vehicles' as a regulation for calculating the pollutants emitted from vehicles. In this regulation, there are the 'Emission factors for each type of vehicle'. Therefore, it is necessary to review the application of the Regulation to the estimation of the required ventilation volume for the road tunnel. In this study, the influence of the strengthened emission regulation in 2015 caused by the case of manipulation of emission volume for the diesel vehicle on the calculation of the required ventilation volume in the road tunnel has been checked. In addition, in this study, the required ventilation volume calculated according to the Standard for Allowing the Emission for the car manufacturing revised by Ministry of Environment and "Emission factors for each type of vehicle" and that calculated according to the EURO emission standard were compared for analysis. This study has implications that it provides the basic design data for calculating the reasonable ventilation capacity of the ventilation system based on the ground for calculating the required ventilation volume.

터널환기 계획시 소요환기량은 환기시설 용량을 결정하기 위한 중요한 인자이며, 소요환기량 산정을 위한 차종별 오염 물질 배출량(환기설계를 위한 기준배출량)은 현재 환경부에서 제시하는 '제작차 허용배출 기준'을 근거하여 산정하고 있다. 그러나, 2013년부터 환경부에서는 자동차에서 배출되는 오염물질을 산정하기 위한 규정으로 '자동차 총 오염물질 배출량 산정방법에 관한 규정'을 고시하고 이 규정에 '자동차 차종별 배출계수'를 제시하고 있다. 따라서 도로터널의 소요환기량 산정시 이를 적용하는 것에 대한 검토가 필요한 실정이다. 본 연구에서는 2015년 경유차량의 배출가스 조작사건 이후 자동차 배출가스 규제강화에 따라 터널의 소요환기량 산정에 미치는 영향을 검토하였으며, 최근 환경부에서 개정한 '제작차 허용배출량 기준'과 '자동차 차종별 배출계수'에 의한 소요환기량과 EURO 배출기준을 적용한 소요환기량을 비교 분석하였다. 또한 소요환기량 산정 근거에 따른 합리적인 환기시스템 용량결정을 위한 기초 설계자료를 제공하는 것을 목적으로 한다.
