This series of papers describe an analysis method on soil-structure interactions through settlements of structures with pile foundations. In part 1, the foundamental equations for this analysis are introduced and some coefficients adopted in these equations are discussed. These equations are introduced under the following assumptions. 1. The one-dimentional consolidation theory is applied to the diluvial clay stratum which underlies the bearing stratum of piles. In this case, the distribution of stress in the diluvial clay stratum can be calculated by Mindlin's equation. 2. Piles are assumed to be elastic columns for axial load. The frictional resistance of the alluvial strata acting on pile surface is neglected. 3. The two cases of steel structure and reinforced concrete structure are treated. The deformation behaviors of these structures are elastic. But in the case of reinforced concrete structure, relaxation of stress due to creep of concrete is considered, too. In one-dimentional consolidation theory, the assumption that the coefficient of volume compressibility m_v and the coefficient of consolidation c_v are constants is usually adopted. In this theory, not only the same assumption but also the case that m_v and c_v are assumed to be variables can by treated.
