• Resumen

  • This article examines the various methods for the design and construction of concrete arches, frames, tunnels and jacked boxes, which cover the whole range of bridges from the smallest culverts to the largest concrete spans in the world. This text should be read in conjunction with the previous two articles in the series, which describe the various in situ and precast techniques for beam bridges1,2. The basic types of bridge described here are:

    • Arch bridges — standard precast arches/portals and bespoke arches • Frame bridges — beam bridges supported by inclined legs • Tunnel bridges — standard precast box culverts and cut-and-cover tunnels • Jacked portal and box bridges — whole spans that are slid or rolled into place CBDG Technical Guide No. 5 on fast construction also gives general guidance on many of these bridge types3.
