ABSTRACT: The Northeast Anthony Henday Drive (NEAHD) project included the construction of 27 kilometers of six- and eight-lane divided roadway, nine interchanges, two road flyovers, eight rail bridges, and two bridges across the North Saskatchewan River, for a total of 47 bridge structures. The project was broken down into three smaller segments. The majority of the middle segment bridge abutments and bridge piers were supported on steel H-piles driven into the underlying clay shale bedrock. The QA program for the bridge pile installations included geotechnical monitoring of pile installations, including PDA/CAPWAP testing on approximately 10 percent of installed piles. This paper describes the results of geotechnical investigations carried out for the middle segment bridge structures, provides a description of the design and construction process, provides back-calculated pile design parameters based on construction monitoring results, and presents comparisons between pile design parameters that were adopted based on the geotechnical investigation results and the results of PDA/CAPWAP tests that were undertaken as part of quality assurance activities during bridge construction.

RÉSUMÉ: Le projet Nord-Est Anthony Henday Drive (NEAHD) comprenait la construction de 27 kilomètres de routes à chaussées séparées de six et huit voies, neuf échangeurs, deux survols routiers, huit huit ponts ferroviaires et deux ponts traversant la rivière Saskatchewan Nord, pour un total de 47 structures de ponts. Le projet a été divisé en trois segments. La majorité des c enfoncés dans le rocheux de schiste argileux. Le programme de qualités de construction pour les installations de pieux comprenait la surveillance géotechnique des installations et des essais PDA / CAPWAP sur environ 10% des pieux installées. Cet article décrit les résultats des études géotechniques réalisées pour les structures de ponts pour le segment du milieu. ocessus de conception et de construction,fournit des paramètres de conception de pieux calculés en fonction des résultats de la surveillance de la construction, et présente des comparaisons entre les paramètres de conception des pieux adoptés en fonction des résultats de l'étude géotechnique et des résultats de PDA / CAPWAP qui ont été entrepris dans le cadre des activités d'assurance de la qualité pendant la construction du pont.
