Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 2,   Pages 239-248 doi: 10.1007/s11709-011-0110-1

Abstract: Surcharge load (e.g. embankment fill) will induce settlement and outward lateral displacement, whilevacuum pressure will induce settlement and inward lateral displacement of a ground.Ideally, combination of surcharge load and vacuum pressure can reduce or minimize the lateral displacementFor the conditions investigated, the results indicate that the outward lateral displacement increasesAlso, it is shown that for a given and condition, lateral displacement reduces with the increase
