non -uniform width box -beam is widely used in the road and mutual overpass in the city and its construction and mechanical property is different from the linear bridge. Besides, the method used in the process mould has essential effect to the analysis results. The particle introduces the application of grillage model in the non - uniform width box - beam through the analysis of the grillage model to one inclined bridge.
