公路声屏障设计标准化研究

Research on Standardization of Highway Sound Barrier Design

文章针对现有公路声屏障设计导致的工程质量良莠不齐、降噪效果不够理想等问题,根据公路声屏障的需求和设计总体思路,分析公路声屏障标准化设计的原则和方法,提出公路声屏障设计在声学、结构与形式、安全、材料、景观、养护和设计文件方面进行标准化的具体要求和内容。本研究提出的公路声屏障标准化设计内容,可以有效解决声屏障设计缺陷导致的工程耐久性较低、降噪效果达不到设计预期等问题,弥补现有公路声屏障设计规范和技术标准要求方面的不足。研究结果可以满足公路声屏障的设计需求和建设要求,降低声屏障位置设置的偏差,增强结构稳固性,提高材料耐久性,减少维护养护成本,为国内公路声屏障设计标准化提供依据。

In view of the problems of uneven engineering quality and unsatisfactory noise reduction effect caused by the existing highway sound barrier design,the paper analyzed the principles and methods of standardizing highway sound barrier design according to the demand for and overall design idea of highway sound barrier.This paper presented the specific requirements and contents for standardization of sound barrier design from the aspects of acoustics,structure and form,safety,material,landscape,maintenance and design documents.The standardized design contents for highway sound barrier proposed in this research can effectively solve the problems of low engineering durability and poor noise reduction effect that are caused by the design defects of sound barrier,and cover the shortage of the existing highway sound barrier design specifications and technical standards.The research results can meet the design and construction requirements of highway sound barrier,reduce the deviation of the location of sound barrier,enhance the structural stability,perfect the safety measures,improve the durability of materials,reduce the cost of repair and maintenance,and provide a basis for the standardization of highway sound barrier design in China.
