针对G um be l分布,考虑了连续样本及非连续样本两种情况,采用M on te-C arlo模拟分析技术,对海港工程设计潮位计算中的矩法(M OM)、最小二乘法(L-S)以及目前流行的线性矩法(L-M)进行了比较研究,同时采用沿海9个潮位站的资料进行了验证...针对G um be l分布,考虑了连续样本及非连续样本两种情况,采用M on te-C arlo模拟分析技术,对海港工程设计潮位计算中的矩法(M OM)、最小二乘法(L-S)以及目前流行的线性矩法(L-M)进行了比较研究,同时采用沿海9个潮位站的资料进行了验证计算。结果表明,与M OM法和L-S法相比,L-M法具有最优的统计性能,建议为工程设计所采用;现有规范推荐的最小二乘法偏于安全,但对不连续系列或当总体分布参数Cv较小时,亦能提供较合理的设计成果。展开更多
