Abstract

Abstract: With the use of Cadna/A software, 3D simulation models are built up for evaluating noise impacts of ground and elevated road traffic on adjacent residential buildings in different cases such as different road conditions, different driving speeds of vehicles, different clearance of the roads to the residential buildings etc. Furthermore, the noise-reduction effects of sound barriers with different clearance to the residential buildings are predicted and analyzed. Finally, a proper standard for sound barrier construction is put forward, which may provide an important technical basis for building layout and environment protection bureau.

摘要： 利用Cadna/A软件，结合实例建立三维仿真模型，针对道路不同，车速不同，预测点距离道路中心线距离不同，预测点高度不同等情况，预测交通道路噪声对预测点噪声贡献值的变化规律。在此基础上，对不同高度和延伸长度的声屏障降噪效果进行预测分析，并采取合适的声屏障，使得第一排建筑地面声环境达标，为建筑布置规划及环保管理部门行政审批提供重要技术依据。
