摘要
高速公路的快速发展引起了严重的噪声污染,缺乏环保性和生态景观效果的传统声屏障不能满足当前绿色高速公路建设的要求,生态型声屏障的研究和建设迫在眉睫。本文总结了目前生态型声屏障的设计原则和分类,以及弧形、梯形、模块化等结构型式在高速公路中的应用。
The rapid development of expressway caused serious noise pollution, lack of environmental protection and ecological landscape effect of the traditional sound barrier can not meet the requirements of the current green highway con- struction, ecological sound barrier research and construction is imminent. This paper summarizes the design principles and classification of ecological acoustic barrier and the application of arc, trapezoid and modular structure in expressway.
