Study on the Pulsating Wind Pressure Characteristics of Fully Enclosed Sound Barriers on Bridges of Beijing-Xiong'an Intercity High-speed Railway
摘要
Abstract
This study investigates the pulsating wind pressure characteristics of full-enclosure steel noise barriers on the Beijing-Xiong'an intercity high-speed railway bridges.A three-dimensional nu-merical simulation model of the airflow field was constructed.It was used to study the spatial distribu-tion of pulsating wind pressure on the barrier surface.The study considered different train operating speeds,including single-train and train-meeting scenarios.Results show that when a single train passes through the noise barrier,the induced pulsating wind pressure time-history response follows a typical pattern of"peak-trough-peak".Under the train-meeting condition,the wind pressure response exhibits the pattern"peak-trough-trough-peak",while the central region maintains the regular"peak-trough-peak"pattern.Further analysis reveals that increasing train speed reduces the wind pressure fluctuation period,indicating higher disturbance frequency at higher speeds,with secondary variations in the wind pressure peaks.关键词
