摘要
Abstract
Ventilation is an important aided system of the multiple working faces in the long and large tunnel construction, which is the necessary condition to ensure the health of the working staff and the running of elec-tromechanical equipment. By testing air quality of the fifth ventilation stage during Bibanpo tunnel construction in site, this study showed that the short supply of air volume, low speed of wind, and high content of dust and CO were the main problems. Extra jet fan and axial fan were installed and the management and maintenance to the ventilation equipment were reinforced to improve the ventilation system. Measured results showed that those measures improved the effects of ventilation and the air quality during tunnel construction. But further improve-ments are needed according to the results.关键词
