| 摘 要： | 为研究高架斜坡道路声场分布规律,根据城市快速路设计规范建立相应的斜坡道路模型,通过微观交通仿真软件结合噪声计算插件对其进行噪声动态模拟,获取三维空间的噪声值及道路垂直截面声场分布图,给出高架斜坡道路的声场分布规律。结果表明:高架斜坡道路上下坡两侧声场分布不对称,上坡一侧声影区界限划分较为明显,而下坡一侧声影区界限划分不明显;下坡侧接受点在高度4~20 m时,噪声值大于上坡侧对称点处的噪声值。

| Abstract: | To investigate the distribution of acoustic field on elevated sloping road, the sloped section models are built according to the Specification for design of urban expressway, and the Paramics microscopic traffic simulation software with noise analysis module is employed to calculate the 3D noise values and obtain the vertical acoustic fields. The characteristic distribution of the acoustic field is summarized with the theoretical analysis. The results shows that the acoustic shadow zone on the uphill side is more significant than that on the downhill side, the noise levels on the downhill side was higher than that on the uphill side within the 4-20 meters range of height. |
