基于光纤Bragg光栅传感器的现役高桩码头结构健康监测系统设计与实施

摘要

The research work on health monitoring technology of wharf in coastal ports is very little at present. According to the damage characteristics of high?pile wharf in coastal ports and particular environment which it works, the mechanical properties of coastal high?pile wharf were analyzed, and the health monitoring parameters were proposed. The health monitoring system of coastal high?pile wharf was established with FBG sensors. And the appropriate structural health monitoring system was designed for standardized front segment of a high?pile wharf in the Tianjin Port. The monitoring plans were proposed, and the sensors and their technical parameters were provided to the purpose. The data acquisition and data transmission subsystem implementation plans and related technical in?dicators were given.%目前,针对沿海港口码头健康监测技术的研究较少.文章根据沿海港口高桩码头结构特点及其所处环境的特殊性,分析了沿海高桩码头结构的受力特点,提出了高桩码头结构的健康监测指标,构建了基于光纤光栅传感器的沿海高桩码头结构的健康监测系统;并依托天津港某高桩码头前承台的标准结构段设计了相应的结构健康监测系统,提出了相应监测的实施方案、传感器选型及性能参数,给出了数据采集与传输子系统的实现技术及相关指标.
