Xdisp – Ground movements arising from multiple embedded wall excavations are derived in Xdisp by summing the effect of each…
Where soil is influenced by more than one excavation, the displacement may be greater than the sum of the calculated displacements. Soil stiffness is strain dependent, therefore later elements of work may give rise to larger displacements. See Nyren et al (2001).
