Investigating the Applicability of GNSS Technology for Monitoring Horizontal Displacement of Wharf Structures

Wharves, vital components of maritime infrastructure, are intricate structures typically anchored by robust pile foundations. These essential facilities face substantial environmental and operational challenges, particularly in deep-water settings where forces are amplified. To maintain structural integrity and ensure safety, precise monitoring of horizontal displacement is of paramount importance. This comprehensive study delves into the application of cutting-edge Global Navigation Satellite System (GNSS) technology for tracking wharf movement. Researchers employed both static and kinematic GNSS techniques to capture detailed displacement data across various time scales, from short-term fluctuations to long-term trends. By meticulously analyzing the collected information, experts can identify subtle displacement patterns, evaluate structural behavior under different conditions, and make informed decisions regarding maintenance and repairs. The findings of this investigation clearly demonstrate the effectiveness of GNSS as a highly reliable and accurate tool for wharf monitoring. This advanced technology offers port authorities and engineers a powerful means to safeguard these critical maritime structures, ensuring their longevity and optimal performance in the face of challenging environmental and operational demands.
