To decide tunnel ventilation shaft location is difficult in the densely populated urban area becauseof public complaint and geographically complicated conditions. If ventilation section becomes long from thesereasons, ventilation efficiency decreases. So, it is necessary to arrange ventilation ports efficiently for uniformair supply and exhaust over ventilation section. In this study, the standards and cases for port installation at homeand abroad were investigated, and the performance of port with various lengths of ventilation sections wasanalyzed. Investigation shows that the port spacing is in the range of 5 to 100 m. Ventilation performance decreasesin the range of 13.39% to 36.04% with the increase of ventilation section length, while ventilation performanceincreases in the range of 12.44 % to 96.7% by the adjustment of opening ratio. Therefore, it was analyzed thatthe optimization for port spacing and opening ratio is required.
도심터널의 환기구는 그 지역의 복잡한 지상여건 및 민원 때문에 설치가 곤란하다. 이러한 문제를해결하기 위해 환기구를 설치하지 않으면, 환기구 사이의 거리가 길어져 환기효율성이 떨어진다. 따라서 환기구역 전체에 균일한 외기 공급 및 오염물질 배출을 위해 환기 포트를 효율적으로 설치할 필요가 있다. 본 연구에서는, 국내외 포트의 설치기준 및 사례를 조사하고, 환기연장 및 포트 설치의 다양한 조건에 대한 성능을 분석하였다. 이러한 조사에 따라, 대부분의 포트 설치간격이 주로 5∼100 m 이하로 규정되어 있음을 알 수 있었다. 환기구간 연장이 증가할수록 환기효율은 13.39∼36.04% 감소하였다. 또한 개도율 조정여부에 따라 12.44∼96.7%의 환기효율 차이가 발생하였다. 따라서 환기구간 연장이 증가함에 따라, 환기 포트의 효율적인 설치간격 선정및 개도율 조정을 위한 최적화 방안이 필요한 것으로 분석되었다.
