Abutment




An abutment is an end support of a Bridge Superstructure .

Abutments are used for the following purposes:

An abutment is also, generally, the point where two structures or objects meet.

Specifically, an abutment may be:
  • the part of a structure that supports an Arch

  • the tooth adjacent to and connecting a Bridge


Abutment is also a term used by Civil Engineer s in Dam Construction ; moving water from a large reservoir to a channel such as a Spillway , there are smooth transition walls at both sides named abutments which minimize the water's energy loss.

Abutment is also a technical mathematical term; it means the final 'sheet' in a Spectral Sequence .
