Monitoring of the anchorage system of the harbour structure of Shahid Rajaei port third phase development project using fiber optic sensor

The design and construction of the harbour structure takes a lot of time and cost to be put into operation, and its regular safety, surveillance and evaluation is no less important than the design and construction stages. The importance of this matter is revealed from the fact that in case of any defects and problems, it will lead to damage to this structure or in a critical condition, it will cause failure and the impossibility usage it. In addition to the loss of huge capital, it may also cause irreparable injuries. In this paper, while introducing the instrumentation of the structural health monitoring system, the investigation and monitoring of the strand anchorage system of the Shahid Rajaei port harbour (phase ۳), which is the first project of the harbour structural health monitoring project in Iran, has been discussed. Among the various control instrumentation used in the structural health monitoring system of the mentioned project, strain gauges with Fiber Bragg grating (FBG) mechanism have been introduced and the obtained results have been analyzed. According to the evaluation on the measurement data and the graphs of control parameters, it can be concluded that the anchorage system of the harbour structure is in a desired condition.
