摘要
以白岩脚隧道为工程依托,采用FLUENT建立白岩脚隧道施工通风的数值三维模型,研究了白岩脚隧道施工期巷道式通风风流场以及爆破后粉尘的扩散规律。相关研究成果可为长隧道巷道式通风的流场分布以及爆破后掌子面产生的粉尘扩散提供参考。
In order to study Based on the Baiyanjiao tunnel,a numerical three-dimensional model of Baiyanjiao tunnel construction ventilation was established by FLUENT,and the Baiyanjiao tunnel was obtained.The wind flow field of tunnel ventilation and the diffusion law of dust after blasting during the construction period of the foot tunnel.The results will provide reference for the flow field distribution of tunnel ventilation in long tunnels and the diffusion of dust generated on the face after blasting.
