Abstract

The bridge suffered long term and short term deformation. Long term deformation can not return to its original shape. Short term deformation (deflection) is a deformed object will return to its original position and shape if detached from its cargo. Suramadu Bridge connect Java Island and Madura Island, which was inaugurated on June 10th , 2009. To control and monitor the bridge, Suramadu Bridge have a system called SHMS (Structural Health Monitoring System). In this research, we analyze the result of GPS measurement on July 1st until July 31st ,2015. To obtain a high position, three GPS antenna were placed in the main bridge and tied with one GPS reference station. For the satellite navigation orbit data we use IGS precise ephemeris in SP3 format. The result of GPS measurement obtained are high position within interval 30 seconds. In this study, the value of vertical deflection on July 1st until July 31st ,2015 on the three GPS antenna located on the middle span of the bridge are a maximum deflection GPS 1 0.2296 m upwards and 0.3184 m downwards from the high point of reference, the maximum deflection GPS 4 0.3315 upwards and 0.3296 downwards from a high point of reference, and the maximum deflection GPS 6 0.1229 m upwards and 0.2949 downwards from a high point of reference. It can be concluded Suramadu vertical deflection value of the measurement using the GPS still meet the tolerances are less then 1,085 m.
