摘　　要：本文综合考虑了复合材料本身及外载的多种不确定因素，首次对复合材料船体总纵强度可靠性问题进行了较全面的研究。考虑了多种失效模式并对复合材料结构本身的各随机变量的分布规律进行了统计分析。给出了一硬壳式玻璃钢艇的实例计算并分析了各种参数对船体结构可靠性的影响，得到了一些很有实际应用价值的结论。A comprehensive and system method is proposed in this paper to analyse the reliabili ty of longitudinal strength of composite ship structures. Various uncertainties of struc tures and environmental loads are considered and important failure modes are developed. Response Surface (RS) method is applied to calculating the probabilities of failure modes.A numerical example, the structural reliability analysis of a single skin GRP boat, is car ried out. The obtained conclusions are valuable for designing reasonable and effective com posite vessels.
