摘要
为完善高桩码头结构在实际复杂运营环境中的受荷响应研究,基于某高桩码头现场监测数据,结合船讯网、现场监控以及监测系统多方位信息融合技术,对高桩码头结构的受荷响应进行分析.结果表明,多方位信息融合技术能够高效准确地判断并识别船舶靠泊监测节点,靠船撞击力较为符合右偏的对数正态分布;PHC管桩应力响应受码头上部岸桥荷载影响明显,同时地基土体约束使泥面下方桩基的应力响应相较于上方桩基出现滞后现象;岸桥移动过程中横纵梁应力监测数据变化明显,且对岸桥荷载作用位置较为敏感.
Abstract
To improve the load response study of a high pile quay structure in the actual complex operational environment,the load response of a high pile quay structure is analyzed based on the field monitoring data of a high pile quay,combined with the multi-dimensional information fusion technology of shipxy.com,field monitoring and monitoring system.The results show that the multi-directional information fusion technology can efficiently and accurately determine and identify the vessel berthing monitoring nodes,and the berthing impact forces are found to be more in line with the right-skewed log-normal distribution.The monitoring data varies significantly during the movement of the bridge and is sensitive to the location of the bridge load.
