Ducks Unlimited Canada report on ice pressures against wier structures phase 1. AD Gould
Material type:
TextPublication details: MB : 1990Online resources: Abstract: Ducks Unlimited designs for hydraulic structures have historically not included any allowance for identation or deformation pressures caused by or anticipated from ice formation within the reservoir or forebay areas.The reasons for this approach are well founded in the economics of each project, the low risk element of structure failure and the unknown but presumed low intensity of acting pressures as evidenced by the isolated cases of structure distress due to ice action reported during annual inspection of the many DU operating structures. As a result, the Chief Engineer of Ducks Unlimited initiated in 1985 the use of a 1 kip/lin ft.ice pressure design force on steel wiers.
