Record #97962:

Effects of structure boundary conditions and snow-pack properties on snow-creep pressures / David M. McClung, Jan Otto Larsen.

Title: Effects of structure boundary conditions and snow-pack properties on snow-creep pressures / David M. McClung, Jan Otto Larsen.
Author(s): McClung, David M.
Larsen, Jan Otto.
Date: 1989.
In: Annals of Glaciology. (1989.), Vol. 13 (1989)
Abstract: Structures in deep snow cover are subject to forces caused by interruption of downslope snowpack deformation components. Resulting creep pressures are often primary design consideration. Here, accurate field data (pressures) and theoretical analysis of problem using linear creep law to define snow deformation are presented. Analytical expressions for pressures are derived. Demonstrates that resulting linear theory underestimates mean pressures by 20%.
Notes:

Annals of Glaciology. Vol. 13 :175-179 (1989).

Keywords: 551.578.46 -- Snow cover and snow patches.
