(57) Abstract:
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
