摘要:

为达到节约投资、降低竖井施工安全风险和结构安全风险的目的,对南大梁高速公路华蓥山隧道运营通风方案进行优化研究。以交通运输部新颁布的规范为立足点,对按照新老规范设计的运营通风方案进行比较,结果表明: 近8.2 km长的华蓥山隧道可由2座竖井分2区段送排式通风调整为左洞全射流纵向式通风、右洞1座竖井分2区段送排式通风,竖井兼作左右洞排烟通道。优化后的运营通风系统配置风机总功率减少1 176 kW(23.1%),近、中、远期稀释污染物时开启风机功率分别降低2 290 kW(60.7%)、2 512 kW(66.6%)和1 892 kW(45.9%)。

Abstract:

The operation ventilation scheme for Huayingshan Tunnel on NanchongLiangping Highway is studied so as to reduce the investment and decrease the safety risk of vertical shaft construction and structure. The operation ventilation schemes designed based on the new specifications and the existing specifications are compared. The study results show that: 1) The original ventilation scheme, twosectioned blowin and exhaust ventilation by two vertical shafts, for Huayingshan Tunnel of 8.2 km long can be replaced by jet longitudinal ventilation in the left tunnel, two sectioned blowin and exhaust ventilation by vertical shaft in the right tunnel and two vertical shafts as smoke discharge channels. 2) The total fan power of the operation ventilation system decreases by 1 176 kW (23.1%) and the fan power for dilution pollutant of short term, medium term and long term decreases by 2 290 kW (60.7%), 2 512 kW (66.6%) and 1 892 kW (45.9%) respectively after optimization.
