摘要
由于博深高速公路石鼓特长隧道受银屏山自然保护区的地形限制,只能从深圳端独头掘进。为确保特长大断面公路隧道的通风效果,通过对石鼓隧道施工通风系统进行论证、计算和分析,拟定了相应的施工通风方案,在隧道施工通风实践中进行验证,该方案设计具有高效、经济和合理等优点,为隧道各工序正常循环提供了有力保障,从而保证了隧道施工的质量与安全。
As Shigu Special Long Tunnel of Bo -shen Expressway being constrained with Yinping Mountain Nature Reserve terrain conditions, tunnel excavation could only be carried out from the Shenzhen side. In order to ensure the effect of tunnel ventilation, in this paper, through demonstration, calculation and analysis on the ventilation system of Shigu tunnel, the corresponding construction ventilation program has been developed. The ventilation practice in this tunnel construction has verified that the design is efficient, economic and reasonable, etc. , which can provide strong guarantees with each normal processing cycle of the tunnel to ensure con- struction quality and safety.
