Calf Robe Bridge Temporary Abutment Stabilization | PLAXIS Real-Life Projects

Online

North American firm GeoStabilization International used PLAXIS 2D for a 2D soil-structure interaction project. The model includes existing H-Pile sections at the bridge abutment. These elements were modelled as embedded beam rows.

The concrete occupying the bridge deck and abutment was modelled with the concrete constitutive model in PLAXIS 2D. The shoring system was modelled as two elements: ground anchors as embedded beams and reinforced shotcrete as plates.

Further, the model included drilled shafts which were modelled as embedded beam elements. To determine ultimate moment capacity of the shaft, as designed and installed by GSI, they used PLAXIS 3D to perform a pushover analysis.

The shaft rebar cage was modelled with beam elements and the concrete volume for the shaft was modelled with the concrete constitutive model.
