ABSTRACT
Under a strip footing plane strain conditions prevail. Scott (1963) has shown that the value of ~u appropriate in the case of a strip footing can be obtained by using a pore pressure coefficient As as
As =0.866A + 0.211 (13.44) The coefficient As replaces A (the coefficient for the condition of axial symmetry) in
Eq. (13.42) for the case of a strip footing, the expression for a being unchanged. Values of the settlement coefficient {3 for circular and strip footings, in terms of A and ratios
HIB, are given in Fig 13.12. Typical values of {3 are given in Table 13.5 for various types of clay soils.
