Abstract：
As for the highway tunnel with massive traffic flow or near the urban area, the lane numbers in tunnel are mostly the same as that of the roadways. However the specified operation speed in the tunnel is often slower than that of the roadway and it results in decline of traffic capacity in tunnel and traffic jam at tunnel entrance. Taking the Longquanshan tunnel of Tianfu airport highway for example, a multi-dimension analysis is conducted in terms of tunnel operation management speed, traffic capacity, construction feasibility and etc., a passenger-freight division based four-tube and ten-lane tunnel system is proposed, namely 2 lanes (freight wagons) +3 lanes (passenger cars)+ 3 lanes (passenger cars) +2 lanes (freight wagons), thus the tunnel has the same traffic capacity as that of roadway and the safety of tunnel construction and operation are ensured.
