Abstract
Beijing-Zhangjiakou High Speed Rail will be completed at the end of 2019. Badaling Station, the only underground station in this line, is the deepest high speed rail station in China with a depth of 102 m. The platform and transforming hall are both narrow spaces, which means acoustic treatment is necessary for the sake of speech articulation. Taking fireproofing, waterproofing, long lasting, culture and visual effect into consideration, ceramic is the most and only appropriate material being used in the underground station. This article will introduce the whole process of design and scale model test for the ceramic Helmholtz resonant cavity.
