Summary:The invention discloses a wind load identification method for attitude decoupling of a wind-induced railway contact network, which comprises the following steps of: detecting actual wind-induced displacement of a contact network positioning point by using field equipment, and establishing a mathematical relation between two-dimensional wind-induced displacement of the contact network positioning point under wind load vector decomposition and a wind load; establishing an overhead contact system finite element model consistent with the overhead contact system structure, applying a load to the overhead contact system finite element model, recording the displacement of a positioning point of the overhead contact system finite element model after the load is applied, and solving an overhead contact system wind load-displacement simulation coefficient in the mathematical relation; and substituting the detected actual wind-induced displacement of the overhead contact system positioning pointand the solved overhead c
