The invention discloses a bridge abutment without an expansion joint. The bridge abutment comprises an upper beam body, a pier, a retaining wall, a first lap plate and a second lap plate, wherein thepier is arranged at the bottom of the upper beam body in a connecting mode, and a gap is reserved between the pier and the retaining wall; the front end of the first lap plate is anchored on the upperbeam body, and the front end of the first lap plate is anchored on soil fillings behind the retaining wall; and the front end of the second lap plate on the soil fillings placed behind the retainingwall is connected with the first lap plate, a cushion plate is arranged below the connecting part of the two lap plates, and an isolation layer is laid between the two lap plates and the soil fillings. According to the bridge abutment without the expansion joint, the problems existing in the prior art are solved, large deformation requirements of the upper beam body and the pier can be achieved, and the overall performance of the bridge abutment is improved.
