The calculation method of horizontal soil spring for spread foundation proposed in this paper is able to assess horizontal soil springs of various individual foundation groups with considering interactions among spread foundations. In addition, the horizontal soil spring of the spread foundation with complex shape can be easily evaluated due to discretizing aggregate of circular foundation. The validity of the calculation method was confirmed by comparing calculated results against those of elastic finite element analysis and elastic theory.
