Pile Design

Using the software APile, the team was able to select piles for the abutments and piers based off of the required axial capacity. A group of four 36 inch diameter piles will be used for both the abutments as well as the piers. An embedment depth of 88 feet is required at the piers while a depth of 101 feet is required for the abutments, putting the piles into the dense sand stratum for both locations. Next the lateral deflection of the piles was determined using the software Group. Five separate load cases were analyzed for the pile group at the abutments and the piers. The lateral deflection at the abutments was under 1 inch for all five load case scenarios. However, the deflection at the piers exceed the maximum allowable deflection. Therefore, the team will need to consider other options for the abutment design.
