ABSTRACT
The Kretek II Flyover is in Yogyakarta. The location of this flyover is in an earthquake potential area and is on an active fault line that crosses the embankment wall of the flyover. GSRW (Geoforce Segmental Retaining Wall) is an MSEW system that will be used for the construction of the approach slab's retaining wall located on the fault line. In the case of this project, GSRW is installed into 3 segments which were separated by dilated concrete. The purpose of the segment's division is to reduce the damage that will occur to the approach slab if there is movement due to faults. Although the displacement distance and the magnitude of the plane caused by the fault cannot be predicted, the GSRW construction is expected to reduce the damage that will occur, because this system can move independently so that the concrete panels are more flexible against shocks. The global stability was then analyzed using PLAXIS 3D software and yield safety factor 1.792 for static analysis and 1.136 for pseudo-static analysis.
