Abstract
Parsons Brinckerhoff (PB) is acting as design consultant for the Nevada Department of Transportation (NDOT) for the Stage II Improvements to the 1-15/US 95 Interchange located in Las Vegas, Nevada. The improvements to the interchange include the design and construction of seven new bridge structures. All seven structures will use drilled shaft foundation systems for support. This paper describes the selection and design of the drilled shaft foundation systems for Ramp N-MLK, a sixteen span precast segmental box girder structure. Subsurface conditions and geotechnical data for the project site are described. A comprehensive design methodology was used, including consideration of service loads, seismic loads, creep and shrinkage. A procedure for determining the equivalent pier length to be used in the structural analysis was developed. A procedure to ensure plastic hinging above ground was developed. This procedure is presented, along with a comprehensive design example.
