摘　　要：为研究船舶吨位与碰撞事故之间的关系,对1311起船舶碰撞事故数据应用聚类分析,按照船舶吨位对碰撞事故的影响程度分为21类.通过对各类数据应用相关分析、曲线拟合及非线性回归分析,建立船舶吨位与船舶碰撞事故数的数学关系模型.研究结果表明:随着船舶吨位的增大,碰撞事故呈现减小趋势.For the purpose of studying on the relation between ship's tonnage and collision accidents,the data of 1311 collision accidents were classified into 21 categories by using clustering analysis method.According to each cluster data,the relation model between ship's tonnage and collision accidents was estab- lished by applying correlation analysis,curve fitting and non-line regression analysis methods.The result shows that the bigger ship's tonnage the smaller the number of collision accidents.
