Research on the Construction of Health Monitoring System and Evaluation Technology of Coastal High Pile Wharf

Through on-site research, research data analysis and engineering experience, the damage characteristics and damage types of high pile wharves in coastal ports were studied and analyzed, and their structural weaknesses and the first damage parts and components were analyzed. Then, a health monitoring system suitable for coastal high pile wharf structure was designed, and four main monitoring indexes, namely, displacement, strain (stress), ambient temperature and structural vibration, were determined through the analysis. Finally, the structural safety assessment method is determined based on each monitoring index of the coastal highpile jetty structural health monitoring system, and the assessment level based on the monitoring data is delineated, and the warning threshold of each monitoring index is determined, so as to lay a theoretical foundation for the analysis of the data and the early warning of the whole coastal highpile jetty structural health monitoring system.
