Model Test on Flow Field Characteristics of the Combined Complementary Double-Hole Network Ventilation with Shaft
Tóm tắt
The ventilation system significantly influences tunnel operation safety, energy savings, and reduced consumption. The Ying'erling highway tunnel proposed a hybrid ventilation system combined with complementary double-hole network ventilation with a shaft. A ventilation model test platform was designed based on similarity theory with a 1/10 transverse length scale. The test platform was used to study the flow field distribution in the hybrid ventilation system under different shaft supply and exhaust conditions. The test results determined the wind speed and pressure distribution at measurement sites in the uphill and downhill tunnel and obtained the influence law of the shaft in the supply and exhaust state on the flow field distribution. A field test of the ventilation performance during tunnel operation showed that the trend of model test results is the same as that of field test results, which verifies the reliability of the test platform. The test results were used to optimize the ventilation control of the Ying'erling tunnel. The study provides an essential guide for the ventilation system design of a long highway tunnel.
