Rnoise 系统中的道路声屏障设计方法

Design Method of Road Noise Barrier in Rnoise System

介绍了一种基于综合数字地面模型以及随机车流声源等效替代和分解技术的户外道路交通噪声分析方法与系统．详细论述了基于该系统的道路声屏障设计与优化方法．该方法能够近似模拟实地各种环境条件的影响，如建筑物、地形、树木、植被以及大气条件等，在一定程度上实现了道路交通噪声和声屏障降效果的可视化设计与评价．

A road traffic noise analysis method and system is introduced, based on the technology of SDTM (synthetic digital terrain model) and line source equivalent substitution and dispersion of stochastic vehicle flow. A geometric design and optimization method of road noise barriers based on the system is proposed in detail. With this method, we can approximately simulate the influences of various environmental conditions, such as buildings, topographic, vegetable covers, and so on. In some degree, visible evaluation and design of traffic noise and effects of road noise barriers are realized.
