摘要： 轨道交通线路两侧声环境预测研究早已成为国际学术界关注的一大课题。轨道交通建成运营后大多靠近或贯穿城市，随之产生的噪声常常会给沿线居民的生活和工作带来严重的影响。为避免该问题继续恶化及有效的预测和控制该噪声，将采用Visual Basic编程语言对轨道交通声环境预测模式的计算过程进行软件开发，同时运用该软件对实地线路两侧声环境进行预测，并将预测值与实测数据进行对比分析，验证该软件的可靠性，以期能使噪声预测工作向着程序化、可视化、简易化的方向迈进。

Abstract: Acoustic environment prediction in the vicinity of rail transit lines has become an international hot topic in railroad engineering. Most of rail transit lines are constructed near or through the urban areas, therefore, the rail transit noise often makes serious impact on the residents in the vicinities of the lines. To effectively control the rail transit noise, Visual BASIC language is adopted to develop the software for rail transit acoustic environment prediction. The results of noise prediction by the software are compared with the measured data of the acoustic environment in the vicinity of a rail transit line, and the reliability of the software is verified. This work is an attempt for routinization, visualization and facilitation of noise prediction by using software.
