Lateral displacement of soft ground under vacuum pressure and surcharge load

Chin-Yee ONG, Jin-Chun CHAI

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

Influence of advanced engineering measures on displacement and stress field of surrounding rock in tunnels

Frontiers of Structural and Civil Engineering doi: 10.1007/s11709-023-0966-x

Abstract: A numerical method was used to investigate the influence of LRAF methods on the stress and displacementThe numerical results indicated that the anchor cable and grouting modification reduced the displacementThe anti-fault cavern resisted the dislocation displacement and reduced the maximum dislocation magnitude, displacement gradient, and shear stress.
