Abstract:
The Penggaron Bridge is one of the longest bridges on the Semarang-Solo Toll Road Section I Km.20. This bridge is in an area with less stable soil conditions. So, the deformation monitoring must be carried out to determine the deformation conditions in the area around the toll bridge. Measurement of deformation in the bridge area of Penggaron was conducted in 2015 and 2016 using the technology of the Global Navigation Satellite System (GNSS). This research was conducted by observing GNSS at eight observation points in the Penggaron Toll Bridge area. Measurements were taken three times over three months in 2018. The velocity rate of the horizontal component of the observation station of the Penggaron Toll Bridge area deformation after elimination of the effect of Sunda Block Rotation become ranged from 1.5 mm/year to 12.1 mm/year. The statistical test results that all observation stations have no movement or no deformation. Four new stations measured and installed in 2018 require another measurement the following year to get a good velocity rate.
