摘要：An abutment especially adapted for use with a bridge is provided whichincorporates lateral containment elements which prevent undesirable lateral shifting ormovement of the bridge during a seismic event. The lateral containment elements areconstructed of varying materials, and form an integral part of the bridge abutment. The
lateral containment elements are positioned laterally of the bridge sill and in abuttingrelationship with the lateral ends of the sill. The lateral containment elements mayinclude mechanically stabilized earth, concrete blocks, concrete blocks with micropile tiedowns, reinforced concrete blocks with shear keys which extend below ground, or steelpiles or beams which are secured in the ground.
