摘　　要：依托成都至蒲江铁路开展技术研究,基于案例从声屏障结构基础、结构立柱和吸声屏板三部分介绍分层拼装式声屏障。从理论分析、结构设计、足尺模型实验、制造生产技术等方面论述临近营业线铁路分层拼装式声屏障技术。通过与传统插板式非金属声屏障和金属声屏障,从经济效益、技术效益、安全隐患等方面进行比较。Based on Chengdu to Pujiang railway to carry out technical research. Based on the case,the layered sound barrier is introduced from three parts： sound barrier structure foundation,structural column and acoustic board. This paper discusses the layered sound barrier technology of railway close to business line from the aspects of theoretical analysis,structural design,full-scale model experiment and manufacturing technology. By comparing with the traditional non-metal acoustic barriers and metal acoustic barriers,the paper compares the economic benefits,technical benefits and safety hazards.
