摘　　要：采用SESAM软件系统,根据中国沿海波浪散布图,对江海直达散货船的波浪载荷进行短期预报和长期预报,对波浪诱导载荷响应及主要载荷参数的长期预报值进行分析,波浪载荷长期预报极值与海船规范计算值比较表明,规范计算公式无法对其波浪载荷作出合理评估,对于此类船型的波浪载荷应用直接计算法计算。According to wave scatter diagram of chinese coastal area,short-term prediction and long-term prediction of wave loads for a river-to-sea bulk carrier are performed by SESAM software.Wave-induced loads response and long-term prediction values of main loads parameters are analysed,which are compared with the calculated values of rules.The comparation shows that the simplified formula of rules can not assess reasonably their wave loads and the direct calculation method has to be adopted to predict detailed wave loadings and distributions for this type of ships.
