摘要
介绍对某港煤码头进行的深水开敞式码头船舶荷载现场试验的测试内容、方法和结果，以及对测试资料的概率统计分析结果．通过对船舶荷载的概率分布规律的研究，提出在可靠度设计中，撞击能量可采用对数正态概率分布、系缆力最大值可采用极值Ⅰ型概率分布作为荷载模型，靠船速度可采用极值Ⅰ型概率分布作为靠船速度计算模型．按南京水利科学研究院建议公式计算的波浪作用下系泊船舶的撞击能量较按规范公式计算的撞击能量与现场试验结果更为接近．
The contents,methods and results of field test for ship′s berthing and mooring loads on a deepwater open sea pier of a port and the probabilistic analysis of test results are described. According to the research on the probability distribution patterns of ship′s berthing and mooring loads,it is advanced that in reliability design the lognormal probability distribution may be adopted as a calculating model for the berthing energy,and the extremum Ⅰ probability distribution for the maximum mooring forces and the berthing velocity.The berthing energy of the moored ships under waves calculated by the proposed formula by NHRI is closer to the results of field test than that by the formula stipulated in the Technical Code for Port Engineering.
