Abstract
A one-dimensional analytical model has been proposed for the average quasi-static snow creep pressure parallel to a slope at the centre of a long rigid structure. The model includes forces due to interruption of creep (internal deformation) and glide (slip of the snow cover over the ground). In reality, the problem is two-dimensional. By a series of two- dimensional finite element calculations, an empirical analytical correction has been found to improve the model. This yields a simple analytical model that provides results within 6% or less of the more complex two-dimensional problem.
