Abstract: This paper takes concrete cracks in road and bridge construction as the research object, and realises intelligent activities such as analysis, reasoning, judgement, conception and decision-making in the manufacturing process through intelligent manufacturing. First, the basic characteristics of intelligent manufacturing technology are analysed, the apparent shape and characteristics of bridge deck cracks are introduced and the bridge deck paving structure with several typical cracks is numerically simulated using finite element software, and the theory of fracture mechanics is used to study the mechanical behaviour of bridge deck pavement working with cracks includes temperature stress, load stress and additional stress caused by differential settlement of the main beam. Finally, the influence of the pavement thickness, modulus, cement concrete cushion thickness and other parameters on the force of the pavement layer is analysed, and the sensitivity analysis of the pavement layer force is carried out.

Keywords: intelligent manufacturing technology; road and bridge construction; bridge performance; bridge crack problem.
