Rocking and Sliding Bankseat Abutment for Concrete Bridge Deck

This paper describes how the online widening of the existing A11 Attleborough Bypass has necessitated the construction of a new concrete integral bridge alongside the existing Queens Road Bridge. The new concrete deck is to be supported on a mixed foundation comprising a bankseat abutment founded on a layer of compacted cement bound granular material supported by a piled raft foundation. This paper describes the design development of a rocking and sliding bankseat arrangement, which will relieve stresses on the abutment induced by seasonal temperature changes and other in-service loadings. It sets out the structural form developed and discusses the design philosophy and issues considered central to the derived solution. An overview of the design approach and experimental investigations undertaken to date to prove the suitability of the structural arrangement are also reported.
