BRIDGE GETS NEW PIER IN ALASKAN REHAB

It was found that seasonal frost was penetrating below the pier wall of the Riley Creek Bridge (in central Alaska) to form an ice lens at its base. This together with adfreeze forces on the piles created jacking forces that raised the pier. When the soil thawed, the pier resettled but not to the elevation of the previous summer. The solution entailed the elimination of the effects of the jacking forces. A major consideration in the design was providing enough room to remove the problem pier. Foundation alternatives for the replacement pier fell into the category of two deeply driven heavy section piles outboard of the existing superstructure to avoid disrupting traffic. Details of the repair procedure are summarized. Qualilty shop and field welding were required for successful fabrication and erection of the replacement pier and hanger bar and pin assemblies, as well as the successful rehabilitation of the bridge.
