摘要:
Increased urbanization and a more intense land use tends to emphasize the landslide problem. This report discusses landslides within the City of Edmonton in general terms and detailed analyses are not presented.Thirty-seven landslide sites are enumerated. Old coal mine subsidence, lateral erosion by the North Saskatchewan River, and construction activity are considered to be the major causes. Man induced landslides account for nearly three-quarters of the slides listed.About one half of the landslides have their seat of failure in the poorly indurated clay shales of Upper Cretaceous age that forms the bedrock. A few are located in fill sections and the remainder are in the glacial lake clays that form the surface deposits of the area.
