高架桥梁交通噪声环境影响预测分析

Environmental impact prediction analysis on elevated bridge traffic noise

以一高架桥为例,选择特征年分析其交通噪声源强,采用线性模式分路段预测交通噪声对道路两侧的空间分布,以此来探讨高架桥交通噪声传播特点以及对周围环境影响的程度。

Taked a girder bridge as an example, selected features annual and analyzed the traffic noise source, used linear mode, and based on the different section, traffic noise on the spatial distribution of both sides of the road was predicted, in order to explore the the Viaduct traffic noise propagation characteristics as well as the extent of the impact on the surrounding environment.
