摘　　要：根据概率极限状态设计原则,结合海洋环境荷载的统计参数,综合考虑基于随机荷载组合的操作情况和极端情况下,计算海上结构物的荷载分项系数,同时在此基础上进行荷载分项系数对可靠度指标的敏度分析。这有助于我国海上结构设计标准的进一步研究。According to the reliability theory of structures,the present paper calculates the partial coefficients of seashore structure which considers circumstance load in case of operation and extremeness of combinations of stochatis loads.Then sensitivity analysis of partial coefficients of seashore structure is based on all above This will accelerate further studies on offshore Structural desiga rula
