声屏障作为噪声污染治理的主要措施之一,已广泛应用于公路、铁路、市政等多种领域。以往人们主要做了高速铁路声屏障风荷载等相关研究,本文在分析高速铁路声屏障风载荷构成的基础上,对北京士兴钢结构有限公司提供的声屏障装配体制作了有限元模型对其抗弯能力进行了仿真研究。通过仿真研究整理出一套声屏障抗弯承载力仿真分析的方法,并利用该方法对不同规格和结构的声屏障产品进行了分析研究,对声屏障开发及技术改进做出了理论上的支持。
As one of the main measures for noise pollution control, sound barrier has been widely used in many fields such as road, railway and municipal administration. In the past, people mostly made researches on the wind barrier of high-speed railway sound barrier. Based on the analysis of wind load of high-speed railway sound barrier, this paper made a finite element model of sound barrier assembly provided by Beijing Shixing Steel Structure Co., Ltd. Bending ability of the simulation study. Through the simulation study, a set of simulation method of acoustic barrier flexural capacity was compiled and used to analyze and study the acoustic barrier products of different specifications and structures, and to provide theoretical support for the development and improvement of acoustic barrier .
