Abstract

Abstract:

In this paper, analysis is made on the ventilation modes for different construction phases, air volume calculation, natural air stress calculation, and air pressurizing under natural air, and the effect of jet ventilation is testified, with the ventilation of AngrenPap superlong tunnel as an example. The results show that jet ventilation mode is rational and can meet construction requirements very well.

Key words: AngrenPap railway tunnel, construction ventilation, jet ventilation, natural ventilation
