Comfortable Evaluation of Bridge-Station Combined Large Span High Speed Railway Station under High Speed Train Load

Abstract

Focusing on the Zhengzhou East Railway Station, which is the larges railway staton in China at present and has the characteristics of bridge-station combined structure. The vibration responses of waiting room floor and business floor caused by high speed train loads are measured and calculated. Then the vibration comfort was evaluated by the code of ATC (1999). The calculation and analysis results showed that: (1) the vibration of waiting floor and business floor under crowd get up loading is small, which can satisfy the comfort demand; (2) the vibration of waiting floor and business floor under high speed train load is bigger because the waiting floor and business floor is more flexible; (3) the vibration comfort under high speed train load can satisfy the demand of relevant code.
