高架道路声屏障设计是近几年来道路与铁路建设中的热门话题,尤其在城市道路或高速公路入城段尤显突出。通过对拟建佛开高速公路联星高架桥路段新型声屏障的设计研究,着重介绍了该声屏障的声学设计、结构设计等内容,并引用斯堪的纳维亚半岛简化的诺模图对联星学校在设置声屏障后的交通噪声进行了预测计算。

In the recent years the sound protective screen design of viaduct is a popular topic of road and railway construction, especially for city roads and city entering section of expressway. With the design research on the new type sound protective screen for the Liangxin viaduct section of the projected Fekai expressway, the acoustic design and structual design etc. of the sound protective screen are mainly introduced in the paper.
