| description | In the recent time the issue of erecting soil sub-structures and constructions at negative temperatures in winter conditions and the areas of permafrost has been really important, so such research studies are very topical. The paper provides for the results of experimental compacting of medium sands of a sub-structure in winter conditions (at the ambient temperature of – 200 … 250 C) in the construction of a complex of protective structures (CPS) preventing floods in St. Petersburg. Heavy and medium-heavy vibratory compactors were used in the experimental sections. Before compaction, sandy soils of the sub-structure with the layer thickness equal to 0.4…0.5 m were placed. For comparison purposes, the paper contains the results of layer-by-layer compaction of such sands in the summer season with application of vibratory compactors and deep-water vibratory plant in the subs-structure of the freeway along the ridge of the protective dam from the side of the Gulf of Finland in the construction of the CPS. |
