Abstract：Based on the fast carbonation experiment on the effect of stress level in the concrete,numerical simulation of the prestressed concrete carbonation depth was carried out.Network models were built and the neural network toolbox of Matlab was used.The complete numerical experiments included train,simulation and prediction.Subentry coefficient γc was provided to reflect structural reliability index in this durability design method.The formula of cover thickness in the durability design was presented according to certain design life and certain reliability index.The cover thickness of the tendons in a framework was calculated to prove this method.The results show that the neural network model has high prediction and simulation capability and the design method is simple and practical,which can be used in structural durability design
