Bridge Foundation Design Methodology in Alaska
This paper summarizes current methodology used for design of bridge foundations in Alaska. These bridges may cross rivers or other roads or railroads (grade separations). Piers and abutments may be supported on spread foundations or piles. This choice typically depends on subsurface conditions. However, piers in rivers or active river floodplains are often supported on pile foundations because of scour potential which would possibly undermine spread foundations. Applicable criteria for design of highway bridge foundations generally follow the 1998 AASHTO LRFD (Load and Resistance Factor Design) Bridge Design Specifications with latest updates. Some of the unique characteristics of bridge foundation design in Alaska are highlighted in this paper.
