ABSTRACT:
The front wall of an overfilled reinforced concrete arch is built from two prefabricated reinforced concrete elements, that are connected in the center by an on-site cast joint, which transmit the vertical loads acting upon them only to the foundation of the underpass, while the horizontal loads, brought about by the earth pressure from the overfill, are transmitted only at the outer edges to the wing wall and to the arch foundation, on one hand, and on the other hand to the arch from the apex portion. In the apex portion, these forces are transmitted from the front wall to the arch by means of metal rods, that transmit only horizontal stresses.
