Method for Determining Deformability of Permafrost Foundations before and after Thawing (Sopsob Opredeleniia Deformiruemosti Vechnomerzlykh Osnovanii do i Posle Ottaivaniia),

Abstract

The results of calculating the displacements of a frozen foundation with a local thaw zone under plate loading are presented. The frozen foundation with thaw inclusions is considered as piecewise homogeneous isotropic elastic medium. Finite element analysis is performed. Based on the calculation results obtained, an error is estimated introduced into the determination of elastic characteristics of a homogeneous thawed foundation and of a piecewise homogeneous frozen foundation with a thaw inclusion. An experimental procedure for permafrost foundations using the 'hot plate' technique is proposed as well as a method for data reduction. (Author)
