In most practical geotechnical problems, the actual domain of soil and rock extends to infinity. For numerical analysis, a finite domain is however commonly used for preparation affinite element mesh which may, however, introduce end effects in computation. Problems involving infinite domain is best modelled with infinite element. The inclusion of body forces (gravity) in the gravity turn-on process with the use of infinite element, however, requires special care and this is considered in the present paper.
