Abstract (en)
[origin: WO03080942A1] An earth overfilled arched structure (10) includes a shallow arch (12) spanning a clear space. The sides of the clear space are formed by curved or straight walls. Solidified zones of earth material against the springs of the arch and/or behind the walls form foundation blocks which are in intimate contact via arch footings with the springs of the arch and/or with the upper part of the sidewalls in such a way that the arched structure delivers most or all of its support forces into the foundation blocks. Also, an overfilled arch bridge system includes a composite arch which has a precast layer and a cast-in-place layer. The system further includes means for reducing bending moments within the overfilled arch. The means include customizing the arch end geometry and prestressing the arch prior to or during loading. Precast arch elements which are formed and shipped in a use orientation. The precast arch elements can include arch footings and the system can include a plurality of precast arch elements. The arch elements can also be prestressed.
