COMPARATIVE ANALYSIS OF THE RESULTS OF STANDARD AND ACCELERATED FIELD TESTS OF PILE FOUNDATIONS IN PERMAFROST SOILS
The relevance of the work consists in the analysis of the results of field control tests of soils with a static load on indentation with full-scale piles, performed according to accelerated and standard methods in conditions of permafrost spreading. The timing of soil testing by piles allows you to...
