On the basis of the traditional structure of noise barrier, this paper seeks aerodynamic load to reduce the variation of maximum surface configuration (porous structure). Using the numerical simulation method, this paper builds a three-dimensional numerical model of deloading type noise barriers and trains. The large fluid calculation software, Fluent, is adopted to conduct simulation calculation of the high-speed deloading noise barriers. This thesis, conducting researches and analysis of the high-speed railway noise barrier aerodynamic load characteristics on the surface, concludes the characteristics of loading surface pressure distribution, time-history features as well as the law of influence factors, which is applicable to deloading sound barrier and lays a theoretical foundation for deloading sound barrier designing.
