摘要
国内早期的铁路声屏障多为直立式,当沿线为高层建筑密集区域时,传统的直立式声屏障降噪效果难以达到要求。目前国内建设的城际铁路增多,为满足环保要求,安装全封闭声屏障的趋势逐渐上升。津兴铁路穿越城区处,两侧居住区繁多密集,需要安装全封闭声屏障来有效地减轻噪声。钢结构骨架是全封闭声屏障的主要受力构件,其加工和安装质量影响着声屏障的稳定性。根据津兴铁路固永特大桥工程实例,对铁路全封闭声屏障的钢结构施工技术进行研究。
Most of the early railway sound barriers in China were vertical.When there are the dense high-rise buildings along the line,the traditional vertical sound barrier cannot achieve the required noise reduction effect.At present,the number of intercity railways under construction in China is increasing.In order to meet the requirements of environmental protection,there is a growing trend to install completely enclosed sound barriers.At the place where the Tianjin-Xingjiang Railway passes through the urban area,there are many densely populated residential areas on both sides.It is necessary to install the completely enclosed sound barriers to effectively reduce the noise.The steel structure skeleton is the main load-bearing component of the completely enclosed sound barrier.The processing and installation qualities will affect the stability of the sound barrier.According to the example of Guyong Bridge Project in Tianjin-Xingjiang Railway,the construction technology of steel structure of the railway completely enclosed sound barrier is studied.
