In some cases, when used in seismic areas of driven piles, designed for vertical loads and moments, their number is not sufficient for the perception of horizontal seismic forces. Therefore tend to increase the resistance of piles horizontal load due to the increase in their number, reinforcement, cross-sectional dimensions, the use of large-diameter pipe piles or inclined piles. However, a more cost-effective and simple solution may be aimed at reducing transmitted to the pile of horizontal forces. One of these ways is to cushion the device from the bulk material between the piles and foundation blocks, carrying the load of the building. However, these foundations retain all the advantages of conventional pile foundations at work on the vertical loads. [1] The features of the behavior of pile foundation with intermediate sand cushion, made by the authors in the Volga State Technological University. The results obtained in model test tray uniform basis indicate the thickness of cushion sand, the number of rows of piles and their cross section.
