Discussion of SNiP 2.02.04-88 Norm "bases and foundations on permafrost soils"

From the Editors: The complexity of construction on permafrost soils, as well as numerous cases of deformation of structures constructed on such soils, calls for an especially careful design and construction approach. The preparation of all editions of the SNiP Norms for design of bases and foundations on permafrost soils (including the last edition 2.02.04-88 of the SNiP Norms), has always been carried out with the participation of many different organizations, and their discussion is of a wide nature. However, after edition of the latest SNiP Norms and their approbation in the engineering practice, continuation of this discussion is highly desirable.For this reason, on publishing the present article without any evaluation of the recommendations contained in it, the Editors ask the specialists in the field of foundation construction on permafrost soils to express their opinions about the questions considered in the article as well as about other criteria of the SNiP 2.02.04-88 Norms.Vorkuta Branch of the "Komigrazhdanproekt" Institute.

Investigation of the operation of pile foundations with dynamic loads

Static and dynamic tests of two single piles and a cluster of four piles with a high foundation mat were conducted in full-scale conditions. A procedure is suggested for processing tests to evaluate the seismic stability of pile foundations, and coefficients are derived for reduction of the load on piles, which fully agree with analogous seismic coefficients of the conditions of operation given in Construction Standard and Rules and make it possible to choose the optimum variant of a pile foundation.Translated from Osnovaniya, Fundamenty i Mekhanika Gruntov, No. 6, pp. 26–27, November–December, 1992.

On chapter II-B.2-62 of construction standards and rules, "footings and foundations of buildings and structures on slumping soils. Designing standards"

The editorial office has received several comments in regard to the new standard specifications for the design of buildings and structures on slumping soils. The articles of M. K. Druzhinin and E. N. Skvaletskii are printed in this issue.Translated from Osnovaniya, Fundamenty i Mekhanika Gruntov, No. 1, pp. 27–29, January–February, 1964
