| 摘 要： | 指出国内外既有船撞桥概率模型的不足之处．在事故记录基础上，根据不同性质航道特征和船舶行驶特点，分别提出狭窄河流、海峡／海湾和内河船撞桥墩概率模型，讨论了各参数取值的合理性，为设计人员认识船撞桥主要风险源和采取合理设计策略提供理论依据．

| Abstract: | The present paper firstly points out the fault of the existing probability models about ship impact against bridges, and based on accident records, new probability models adapting to the characteristics of narrow waterway, strait/bay waterway and inland waterway are built. Also, the reasonability of parameter values is discussed. The research work can help bridge designers know well the main causes of risk and adopt reasonable designing strategies. |
