ASSESSMENT OF EMBANKMENTS STABILITY IN VIEW OF CONSOLIDATION PROCESSES IN FOUNDATION SOIL IN PERMAFROST

摘要

The report focuses on issue of providing the stability and deformability of embankments,constructed in areas where permafrost.It is known that the construction of complex engineering and permafrost conditions require special measures to ensure the strength and stability of subgrade.The aim of the work was to evaluate deformability of embankments during thawing basis, with much attention paid to the simultaneous study and account for the influence of thermal processes that alter the initial temperature field is established at dumping mounds, and the process of consolidating soil foundation.The paper proposes a tree-layer model of the thawing weak base for the calculation of subgrade deformability, given the comparative calculations for various schemes, the analysis results.
