Centrifuge Study of Spill-Through Abutments
One of the most common types of bridge abutment employed in road construction is the open or spill-through abutment. The design approach for this type of abutment was originally developed in 1948, and it is somewhat surprising that the method of design has remained virtually unchanged since that time, in view of the major developments in geotechnical engineering that have occurred. In this paper, the results of a centrifugal model study were to investigate the performance of a range of models, constructed with different ratios of pier diameter to both spacing and height, as well as to carry out a limited assessment of the influence of the geometry of the pier cross-section. In addition to providing a proposed revised approach to the design of spill-through abutments, consideration is also given in the paper as to how the construction process may influence the design.
