| Abstract: | In this paper, the time-varying technical condition of bridge is analyzed. According to the fuzzy evaluation theory and Markov process method, the prediction models for bridge technical conditions and the maintenance cost are got. Numerical examples show that the method can be used to find the development law of bridge technical condition and predict the potential danger, so that the maintenance budget can be optimized as far as possible, bridge safe and rational using are ensured in service period. |
