Abstract
Geotechnique of Saskatoon is the integration of geology, geohydrology and soil mechanics in an urban area. The bedrock sediments include Upper Cretaceous Lea Park, Judith River and Bearpaw formations and glacial deposits include Quaternary Empress, Sutherland and Saskatoon groups, representing at least six glaciations. The Lea Park and Bearpaw formations are composed of noncalcareous, grey, nonmarine silts and clays, separated by noncalcareous, carbonaceous, grey, nonmarine, deltaic sand and silt of the Judith River Formation. The Empress Group is composed of sand and gravel, restricted mainly to bedrock valleys. The Sutherland Group is composed mainly of tills of the Mennon. Dundurn and Warman formations. The Saskatoon Group is composed of lower and upper till units and intervening Riddell Member sand of the Floral Formation, till of the Battleford Formation and lacustrine silt and clay (Grasswood Allomember) and deltaic sand and silt (Furdale Allomember) of the Haultain Alloformation. Subsidence from collapse as a result of dissolution of Devonian salts has affected the bedrock sediments and the Sutherland Group. The geohydrology is represented by a system of 6 aquifers and 10 aquitards of Cretaceous age or younger. The application of soil mechanics in Saskatoon involves a range in conditions from high bearing capacity overconsolidated tills for foundations, to instability in open excavations and valley slopes in normally consolidated lacustrine clays. Data storage is managed by numerous government agencies and private consultants.
