How to Design Urban Rail Transit Sound Barriers Rationally?

Urban rail transit primarily includes systems such as subways, light rail, monorail, suburban rail, modern trams, and magnetic levitation transport. The installation of sound barriers is essential to reduce the noise generated by these transit systems during operation. How can we design urban rail transit sound barriers reasonably? Here are some suggestions.

Based on the noise management target values and acoustic design, the shape, dimensions, structural methods, and additional treatment measures for the sound barriers should be planned. It is important to predict the noise reduction effects of different schemes to ensure that the sound barriers effectively minimize noise impact on the surrounding environment.

In terms of structural design, sound barriers must be safely and securely erected at their designated positions. This involves both load-bearing structural design and general structural design. The load-bearing design should consider the strength, stiffness, and safety of the materials, while the general design should focus on meeting acoustic requirements and facilitating easy installation.

The structural method of the sound barriers should be determined based on the surrounding environment and terrain conditions. Common materials include concrete, steel plates, and plastic. These materials must possess excellent weather resistance, fire resistance, corrosion resistance, and compressive strength.

The construction of sound barriers should strictly follow national standards. Each step, including foundation treatment, masonry or fixation, support frame arrangement, mesh layout, plastering, and aesthetic finishing, must be carefully executed to ensure construction quality.

In the design of sound barrier projects, it’s also necessary to consider terrain and environmental requirements, geological conditions such as soil and groundwater, potential impacts during construction, and various design specifications.

Additionally, the design of sound barriers should integrate with the overall urban rail transit project, city planning, and landscape, ensuring that while functional requirements are met, the visual effect is also aesthetically pleasing.

Rationally designing urban rail transit sound barriers involves scientific planning and construction to effectively reduce noise pollution and improve the quality of life for city residents.
