Abstract

The airport is a pivotal infrastructure project, serving as a hub for parking, transporting, and maintaining aircraft carrying passengers, freight, and cargo. However, the substantial usage of the airport leads to the challenge of land subsidence, necessitating ongoing monitoring and assessment. This study focuses on monitoring land subsidence at Suvarnabhumi Airport, Thailand's premier international airport catering to passengers and aircraft. In a lowland area with soft soil, applying advanced technology becomes imperative for continuous monitoring and analysis of subsidence over time. Employing InSAR Time-Series technology, researchers processed data from Sentinel-1 satellites spanning October B.E. 2017 to December 2023 to analyse the evolving conditions at Suvarnabhumi Airport. Results reveal that the most significant subsidence occurs in the Runway and Taxiway areas, with values ranging between -9.1 and 5.1 millimeters. per year. This subsidence is likely attributed to the constant heavy air traffic on these surfaces. Continuous monitoring and evaluation are crucial to planning effective maintenance. InSAR technology is valuable for monitoring land subsidence or displacement, alleviating data constraints and streamlining operational processes.
