The influence of lateral deformation of deep marine soft soil underlying embankment on its settlement through the triaxial and plane strain creep tests is studied. The result indicates that the relationship between the initial stress and strain is nonlinear
the shear stress produces unrecoverable lateral deformation which is an important component of the settlement. The lateral deformation expands all the time under undrained condition
while it not only expands but also shrinks under drained condition. There are corresponding relationships between shear stress level and the process of lateral deformation
when the shear stress level is low
the influence of lateral deformation on the settlement of roadbed is not so distinct
when it is high
the influence should not be neglected and it appears along the whole course of settlement.
