Abstract
This paper presents the results of a three-dimensional finite element analysis on a geosynthetic-reinforced bridge abutment. Examples on the use of mechanically stabilized earth bridge abutment in north America are first presented. A three-dimensional finite element analysis on a 4.8 m high, 14 m wide geosynthetic-reinforced bridge abutment was performed to investigate the 3D behavior of the geosynthetic-reinforced bridge abutment and the load carrying capacity of the bridge abutment in the three-dimensional space. The results are then presented in a way that the three-dimensional behavior of the abutment can be identified in terms of wall displacements and reinforcement forces. It is shown that the wall facing displacements as well as the reinforcement forces in the abutment are smaller than those computed based on a plane strain approximation.
