Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 3,   Pages 429-447 doi: 10.1007/s11709-022-0913-2

Abstract: , respectively, and the lateral effective stress of the different stirrups was calculated based on theMoreover, a damage-constitutive model of CAC considering the lateral stress was set up based on damageHowever, an increment in the lateral strain was observed with an increase in the axial strain.The lateral stress model showed a good agreement with the experimental data, and the proposed damage-constitutivemodel had a good correlation with the measured stress−strain curves.

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
