摘　　要：目前道路声屏障设计以经验设置为主,缺少具体的工作流程规范,导致声屏障实施过程中调整比例大,整体设计质量不易得到保证。文中以实际工程为依托,介绍基于数学模拟的“等声线包络法”及其相应的计算架构,并揭示了道路声学模拟的计算逻辑和内容。经验证,该计算方法操作便捷、简单,计算结果满足工程设计需求,可为进一步规范化道路声学设计提供技术参考,建设者也可根据相应计算成果提升建设质量。At present,the road noise barrier design is mainly based on experience,and there is no corresponding specific workflow,which leads to a large proportion of adjustment during the implementation of the noise barrier,and its overall design quality is not easy to be guaranteed.The“Isoacoustic Envelope Method”based on mathematical simulation and its corresponding computational architecture are introduced through practical engineering cases,and the computational logic and content of road acoustic simulation are revealed.The results show that the calculation method is convenient and easy to operate,and the calculation results meet the requirements of engineering design.It can provide important technical references for further standardizing road acoustic design,and builders can also improve the construction quality based on the corresponding calculation results.
