Dr. Jianping Jiang is the National Practice Leader for Bridges and Civil Structures with WSP in Canada. He is responsible for the firm’s Bridge Engineering Practice in Canada. He has published over 47 technical papers in international journals and conference proceedings. He has successfully completed many challenging bridge projects for both public and private sector clients, ranging from less than one million to over hundreds of millions in capital costs. He has designed and inspected various types of bridges including highway, railway, LRT, and pedestrian bridges in British Columbia, Alberta and overseas. Dr. Jianping is an expert and industry leader in bridge seismic analysis and design, complex bridge projects, and design-build and P3 delivery.
DESIGN AND CONSTRUCTION OF HIGHWAY 29 REALIGNMENT BRIDGES FOR BC HYDRO’S SITE C CLEAN ENERGY PROJECT
BC Hydro’s Site C Clean Energy Project is to build a third dam and hydroelectric generating station on the Peace River in northern British Columbia, Canada. When completed, it will provide 1,100 megawatts (MW) of capacity and produce about 5,100 gigawatt-hours (GWh) of electricity each year — enough energy to power the equivalent of about 450,000 homes per year. The realignment of six segments of Highway 29 over a total distance of 30 kilometers is one of the key components of the project. Highway 29 realignment requires the design and construction of five new bridge crossings, ranging in length from 150 m to 1050 m, over a wide range of valleys and channels of the Peace River tributaries where various geohazards were identified including rare extreme landslide events that could generate fast-moving waves in the reservoir impinging large forces on bridges. A performance-based approach was used in the design of bridge structures under Landslide Generated Wave (LGW) impact loading. Bridges close to the dam have their decks elevated more than 50m above the existing ground with the tallest piers up to 47m. After being inundated by the reservoir, only about 10m of piers will extend above water level. Many bridge elements were standardized including steel plate girders, precast deck panels, hollow pier columns, pile foundations, bearings, and joints for consistency among all bridges on the project.
