城市高架路全影型声屏障的设计优化与施工

Design Optimization and Construction of a Full-Closed Sound Barrier for a Urban Elevated Highway

结合嘉闵高架路南南延伸段沿线声环境敏感目标的保护要求和现场实际状况,采用全影型声屏障进行隔声降噪设计。在施工阶段,在原设计的基础上对全影型声屏障进行安全、声学、结构和景观等方面的优化和三维建模可视化设计。通过优化设计,有效提高现场施工的效率,缩短工期,确保项目按期完工,使项目的技术创新得到具体实施,实体质量可靠,功能效果显著。

The full closed sound barrier is designed for the south extension of Jia-min highway according to the protection re- quirements of the acoustic environment sensitive targets. The preliminary design of the sound barrier is optimized in terms of the safety, the acoustic performance, the structure design and the appearance. The landscape with the sound barrier installed is previewed by means of the 3D visualization, The process proves to be effective in implementation of the project.
