Book excerpt: This report considers a floating ice sheet supporting a crowd of people who are free to assume any distribution. The problem is analyzed when the people gather into a long strip, two strips, or a circular area, all of which may vary in size. The worst possible size is determined for the safe bearing capacity in each case. Upon comparison of the results, a single equation is suggested for practical use. (Author).

Book excerpt: The mathematical theory for the bearing capacity of river ice for vehicles is presented. The floating ice sheet is assumed to have simple supports at the shore line. Solutions are presented for loads uniformly distributed over circular and rectangular areas. Numerical evaluations are made for a number of vehicles and the results presented in graphical form.

Book excerpt: The problem investigated in this thesis is the prediction of the deflection and stresses in a floating ice sheet under loads which act over a long period of time. This problem is currently important for oil exploration offshore in the Arctic. A review of analytical methods for predicting the bearing capacity of an ice sheet is given. The problem is formulated by assuming the ice is isotropic with a constant Poisson's ratio. The shear modulus is assumed to obey a linear viscoelastic model. The specific model selected is a series of one Maxwell model and two Voigt models. One of the Voigt models has a negative spring constant which produces tertiary creep. The ice model exhibits a primary, secondary, and tertiary creep response, similar to that observed in uniaxial creep tests of ice. The material properties in the viscoelastic model may be a function of the vertical position in the ice sheet, but all these material properties must be proportional to the same function of position. Using the thin-plate theory for the floating ice sheet, the solution is obtained for the deflection and stresses in the ice sheet for primary, secondary, and tertiary creep regions. It is then shown that for a load that is not distributed over a large area, the time-dependent part of the deflection and stresses is relatively independent of the load's distribution. For the elastic case, the stress significantly depends upon the load's distribution. Results are given for the deflection and stresses as a function of time and distance from the load. The maximum deflection and stresses occur at the center of the load. At this point the deflection increases with time, while the stresses decrease; i.e., the stresses relax. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The bearing capacity of a floating ice sheet is of considerable interest. The pattern of ice thickness vs tensile stress for a fixed load and fixed ice properties was examined and showed some constant relationships. It proved possible to completely describe the ice thickness-tensile stress pattern in terms of a single number. When the load was changed by increasing the payload but not altering the geometry of the load pattern, other relationships were found that described the tensile stress in the ice sheet for any combination of payload and ice thickness. This provides a simple method of finding tensile stress in the ice that can be used in the field.

Available in PDF, EPUB and Kindle. Book excerpt: This state-of-the-practice report on the design and development of roads and airfields is the eighth monograph in a series prepared by the Technical Council on Cold Regions Engineering of the American Society of Civil Engineers. Previous reports in the series covered such topics as frost action and its control embankment design, and arctic coastal processes. This book discusses such topics as: 1) Route-location/siting; 2) frost action; 3) design for permafrost conditions; 4) low temperature cracking; 5) maintenance; 6) use of geosynthetics; and 7) materials specifications and testing. This monograph contributes a substantial amount of new material to the Cold Regions Engineering series.
