Geotechnical and Seismic Design of Innovative Roger Pierlet Bridge and Approach Structures
The existing Roger Pierlet Bridge located south of Cloverdale, near Vancouver, British Columbia (BC) carrying two lanes of traffic to the US border was constructed in the early 1970's. During the original construction, a ground failure in very soft and sensitive Cloverdale Clay occurred at one south embankment section, triggering additional ground remedial measures before the embankment was finally constructed to the design elevation. In June 2004, the Ministry of Transportation (MOT) of BC called for a design-build proposal to twin the Roger Pierlet Bridge as part of the Highway 15 Border Infrastructure Program. Buckland & Taylor Ltd., the bridge engineer for the West Shore Constructor's team, developed an innovative design decreasing the number of spans from 20 to 5 and using innovative lightweight approaches consisting of parallel sheet pile walls containing EPS (expanded polystyrene) and hog fuel (sawmill wood byproduct). The capital cost of the new bridge was estimated to be significantly lower than that of a conventional 20-span new bridge. The innovative design was selected by the MOT. The construction of the new bridge started in January 2005 and is anticipated to be completed in early 2007. This paper presents the key geotechnical and seismic issues related to the design and construction of the new lightweight approach structures and the bridge foundations.
