摘　　要：赣深高铁涉及深圳市城市建成区,结合城区路段噪声敏感建筑物以及环评降噪要求,对半封闭式声屏障从梁型、结构型式、安装方式等方面进行研究,以期选择最佳的半封闭声屏障,为高速铁路采用半封闭声屏障降噪设计提供了实际工程案例,为后续解决高速铁路城区段噪声问题提供了借鉴。The Ganshen high-speed railway involves the urban built-up area of Shenzhen city.Combining the noise sensitive buildings in urban sections and the noise reduction requirements of environmental assessment,the semi-enclosed sound barrier is studied from the aspects of beam type,structural form,installation mode,etc.,in order to select the best semi-enclosed sound barrier,which provides apractical engineering case for the noise reduction design ofhigh-speed railway with semi-enclosed sound barrier.It provides reference for solving the noise problem in urban section ofhigh-speedrailway.

关 键 词：高速铁路 半封闭式声屏障 降噪设计
