广深港铁路客运专线狮子洋隧道采用CRTSⅠ型板式无砟轨道，为减少振动、噪音及提供舒适度，在CA砂浆层下设置弹性减振垫层，此工艺在国内时速350km的铁路客运专线项目中首次应用。详细介绍弹性减振垫层的设计、材料控制及铺设技术，对同类工程有借鉴意义。
廣深港鐵路客運專線獅子洋隧道採用CRTSⅠ型闆式無砟軌道，為減少振動、譟音及提供舒適度，在CA砂漿層下設置彈性減振墊層，此工藝在國內時速350km的鐵路客運專線項目中首次應用。詳細介紹彈性減振墊層的設計、材料控製及鋪設技術，對同類工程有藉鑒意義。

Since type-CRTS Ⅰ ballastless tracks are used in the Shiziyang Tunnel of the Guangzhou-Shenzhen-Hong Kong pas- sengers-oriented railway, in order to reduce the vibration and noise and to improve comfort, the elastic vibration-reducing cush- ioning layer is provided under the CA sand bed, the process of which is applied to the project of passengers-oriented,350 km/h- operated railways at home for the first time. The design, material control and laying techniques for the elastic vibration-reducing cushioning layer are dealt with in detail in the paper, which may serve as a useful reference for projects of similar types in the future.
