| 摘 要： | 建立基于模糊马尔科夫链的钢筋混凝土桥梁劣化预测模型，对桥梁结构劣化等级的划分及模糊劣化状态的确定方法进行阐述。针对马尔科夫链应用的关键问题一状态转移概率矩阵的确定，提出基于对状态转移概率优化反演的简化逆阵方法。通过某桥梁工程劣化预测实例，验证该方法的有效性。

| Abstract: | By establishing the prediction model for deterioration of reinforced concrete bridge based on the fuzzy Markov Chain,this paper expatiates the classification of deterioration grades of bridge structure and determination methods for fuzzy deterioration states.Aiming at the critical problem in application of the Markov Chain-determination of state transition probability matrix,the paper proposes the simplified inverse matrix method based on optimization and inversion for state transition probability.The effec... |
