Experimental Design for a Half-Scale Shaking Table Test of a Geosynthetic-Reinforced Soil Bridge Abutment
This paper presents an experimental study on the seismic performance of a half-scale geosynthetic-reinforced soil (GRS) bridge abutment. Experimental design of the scale model followed established similitude relationships for shaking table testing in a 1 g gravitational field. This involved scaling of model geometry, reinforcement and backfill stiffness, bridge load, and characteristics of the earthquake motions. The GRS abutment was constructed using well-graded sand, modular facing blocks, and uniaxial geogrid reinforcements with a vertical spacing of 0.15 m in both the longitudinal and transverse directions. The bridge deck was placed on the GRS abutment at one end and supported by a concrete wall resting on a sliding platform off the shaking table at the other end. The table was connected to the base of the support wall with steel beams to transmit the table motions. The measured lateral facing displacements and bridge seat settlements during application of a series of earthquake motions in the longitudinal direction are presented and indicate good seismic performance of the GRS bridge abutment.
