Comparative Analysis of the U.S.S.R. Construction Codes and the U.S. Army Technical Manual for Design of Foundations on Permafrost

A comparative study was made of design criteria and analytical methods for footings and pile foundations on permafrost employed in U.S.S.R.

Description
Summary:A comparative study was made of design criteria and analytical methods for footings and pile foundations on permafrost employed in U.S.S.R. Design Code SNiP II-18-76 (1977) and U.S. Army Cold Regions Research and Engineering Laboratory Special Report 80-34. The absence of adequate constitutive equations for frozen soils and of rigorous solutions of the boundary problems has made it necessary to incorporate (explicity or implicity) various safety factors in the foundation analyses. From the review it is concluded that the principal difference between these practices is in the assessment and application of appropriate values of safety factors, which leads to a substantial discrepancy in the dimensions and cost of footings and pile foundations in permafrost.
