大连港码头荷载的统计分析

Statistical Analysis of Load of Dalian Port Dock

以大连港为例，阐述了港口码头如何收集荷载子样，选择任意时点荷载强度的概率分布．用平稳二项随机过程模型，推导出设计基准期５０年内是大荷载值的分布．最后给出码头荷载均值、方差、变异系数和码头的设计荷载值．

This paper gives an example of collecting the subsamples of load and choosing the probability distribution of arbitrary time point's load intensities for the Dalian Port.From the model of stable binomial stochastic process the pro bability distribution function of maximum load for design reference time of 50 years has been derived. At last, the mean values, coefficients of variation and the design load values for dock design have been presented.
