In recent years in analysis of causes of diseases in combined truss arch bridges, existence of transverse bias effect of live load has been always one of problems focused on research by engineering technicians and researchers. In combination with load test of 5 combined truss arch bridges, this paper analyzes and concludes the laws and features of load bias factor of combined truss arch bridges by means of test data in static load test of bridges concerning bias loading conditions, and the associated results can provide a reference for design of similar bridges.
