The vertical stress is given by: σz = 3P 2π z3 R5 = 3P 2πR2 cos3 β = I P z2 () where I is termed an influence factor. One of the several reasons for assuming that the soil consolidates in response to the change in vertical stress is the relative simplicity of the equations, which do not contain Poisson's ratio.

Published by the Naval Facilities Engineering Command (NAVFAC) in Norfolk, Virginia. EXCAVATIONS Open. For elastic half space, the classical solutions for vertical and horizontal point-loads acting on the surface are used to develop the flexibility matrix of the foundation.

Inverting this matrix yields the soil stiffness matrix, which—when coupled with the stiffness matrix of the structure—gives the stiffness matrix of the structure. 30 RAFT FOUNDATIONS-DESIGN AND ANALYSIS K, = SR,r Where K, = Coefficient of vertical subgrade reaction, Kips per cu ft (metric tons per cu m) K, basic value of coefficient of vertical subgrade reaction for a square area with width b = 1 ft ( m).

'= Kips per cu ft (metric tons per cu m) b = Width of footings, ft (m) S = Size or shape factor. It is reasonable to assume that, in practice, the high elastic contact pressures in the edge region of the raft will be reduced by local yield of the soil.

However, a subsequent non-hnear analysis indicates that the change in raft flexure is rather smah in this instance.
