［摘要］地下空间的发展不可避免使得人们的工作、居住、交通环境更为交融，而交融中的各种交通振动与噪声给地下空间内部及其结构带来了一定的不利影响。不仅给地下空间的主体结构安全带来隐患，也严重影响着人们的舒适度。珠江新城核心区市政交通项目隔振降噪设计有效提高了花城大道隧道底部地下空间结构安全度与舒适度，通过介绍花城大道隧道穿越地下空间时进行隔振降噪处理的必要性、目标要求、具体方式和计算方法，为类似工程项目提供参考。

Abstract:The development of underground space inevitably makes people′s  working, living and the traffic environments more integrated, and all kinds of  traffic vibrations and traffic noises in the integration bring some adverse effects to the underground space and its internal structure. It not only brings the security risks to the main structure of the underground space, but also seriously affects people's comfort. Vibration isolation and noise reduction design of municipal transport project in core area of Zhujiang New Town effectively enhances safety and comfort of underground space structure at the bottom of Huacheng Avenue Tunnel. The necessity of vibration isolation and noise reduction, objectives and requirements, specific methods and calculation methods for Huacheng Avenue Tunnel crossing underground space were introduced, which provides a reference for similar projects.

Keywords:underground space; vibration; noise; vibration-isolated bearing
