THE ANALYSIS OF STRAIN DATA OF THE MONITORING SYSTEM IN THE CHIANG-KAI-SHEK INTERNATIONAL AIRPORT

Abstract: In January 2002, a research experiment installed a number of sensors in taxiway N1 in the northern field of the Chiang-Kai-Shek (CKS) International Airport during a scheduled slab repair. The sensors measure changes of slab behavior in response to various environmental factors and different aircraft loading. The slabs are 6 m wide, 7 m long and with 41 cm in depth. A total of 102 monitoring devices were installed. These included the H-bar and the Dowel-bar strain gauges; position gauges, temperature gauges, and moisture gauges; as well as optical fiber sensors. This paper mainly focuses on the analysis of the instant data recorded by H-bar strain gauges generated by the taxing aircraft, including the variation of strain induced by aircraft of different gear configurations, the strain at different depths and the joint, as well as the comparison between the finite element method (FEM) analysis results and the field data
