摘　　要：隧道交通噪声主要来源于轮胎与路面接触噪声,建立隧道内交通噪声数值模拟模型,通过有限元计算,分析了隧道不同位置交通噪声的变化规律。数值模拟结果表明,隧道内不同位置的交通噪声大小差别较大,随着距隧道洞口的距离增大,噪声水平增加,隧道中部比隧道进出口处噪声高约8～10 dB,比隧道外高16～18 dB,隧道洞体对隧道内交通噪声影响较大。通过现场测试隧道交通噪声,结果表明隧道内交通噪声数值模拟结果与实测结果较为吻合,说明所采用的数值模拟模型是可靠的。Tunnel vehicle noise is mainly from the contact of tire and pavement surface. Numerical simulation model of tunnel vehicle noise was developed to simulate the change of tunnel vehicle noise in different parts of tunnel with FEM. The result shows that tunnel vehicle noise is variable in different parts of the tunnel, vehicle noise level gradually rises with the distance increase from tunnel entrance, and vehicle noise level at tunnel middle part is 8 - l0 dB higher than that at tunnel entrance, and it is 16 - 18 dB higher than that at tunnel outside, so tunnel has great effect on vehicle noise. Additionally, vehicle noise was in - situ tested to verify the consistency with numerical simulation, which shows that numerical simulation model is reliable.
