摘要
研究了单车在隧道内行驶时,隧道尺寸对洞口噪声的影响。重点讨论了横截面和隧道长度等对洞口噪声级的影响,并给出了一个对矩形和半圆形截面隧道通用的洞口噪声预报模式。
The influence of tunnel dimensions on noise around tunnel mouth was studied, with a single car running through it. The influence of cross-section and the length were emphatically studied. And a general predicting mode was given in this paper.
