摘　　要：随着都市圈内铁路建设的持续发展,铁路进入城区产生的噪声问题逐渐成为公众关心的重要问题。声屏障是目前常见的主动降噪手段,城区内高层住宅声环境质量受铁路噪声影响较大,对声屏障降噪效果要求较高,可采用封闭式声屏障工程解决。基于对某封闭式声屏障工程设计、降噪效果模拟及实测等方面的研究,并与部分国内封闭式铁路声屏障降噪效果进行比较,认为封闭式声屏障在城际铁路工程中具有较好的应用效果,可为同类项目提供借鉴。With the continuous development of railway construction in the metropolitan area,the noise caused by railway entering the urban area has gradually become an important issue of public concern.Sound barriers are currently a common active noise reduction method.The sound environment quality of high-rise residential buildings in urban areas is greatly affected by railway noise,and there is a high requirement for the noise reduction effect of sound barriers.Enclosed sound barrier engineering can be used to solve this problem.Based on the research on design,noise reduction effect simulation and measurement of a enclosed sound barrier,and compared with some domestic closed railway sound barriers,it is considered that the closed sound barrier has better application effect in intercity railway engineering,which can provide reference for similar projects.
