| Abstract:The ventilation layout and ventilation equipment of the longest expressway tunnel (Maijishan tunnel)construction with blind heading interiorly were introduced, the relevant parameters were calculated according to the standard methods, the verification of numerical simulation for the construction ventilation scheme was processed based on the finite element fluid dynamics software FLUENT. Some problems encountered during the ventilation process and the solutions were described to obtain a good tunnel ventilation effect and create a comfortable and efficient work environment. |
