In this paper，the existing wind and dust suppression net projects are taken as an example to address the value problem of parameters in the structural design of wind and dust suppression nets. Specifically，by combining wind tunnel tests and specifications，the structural design method of wind and dust suppression nets in bulk cargo yards is discussed，and then we focus on analyzing the method of determining the values of parameters such as the structural shape factor of wind loads and the wind vibration coefficient. The results reveal that the wind and dust suppression nets，as an important wind and dust suppression measure for bulk cargo（coal and ore）yards in port engineering，are characterized by clear force，clear load transfer paths，and convenient construction. On the basis of the wind load calculation formula in Load Code for the Design of Building Structures，reasonable selection of design parameters such as the wind vibration coefficient and structural shape factor can ensure the safety，stability，economy，and reasonableness of structure.
