    • Abstract
  • Due to green building railway requirements, noise barrier, as an effective noise reduction measure, will be widely constructed, and the air turbulent force caused by high speed trains must be taken into account during design. The whole process of train passing is simulated using the fluid calculation software CFX, involving models of train and noise barrier, air and ground, thus the air turbulent force curve is obtained. Results agree well with the foreign published results. This paper provides the air turbulence load for the structure design of noise barrier.
