Estimation of Liquefaction-Induced Manhole Uplift Displacements and Trench-Backfill Settlements
Publication: Journal of Geotechnical and Geoenvironmental Engineering
Volume 138, Issue 4
Abstract
A simple method to predict the uplift displacement of a manhole and trench-backfill settlement due to liquefaction is proposed. The conventional equilibrium of vertical forces acting on a manhole is solely a function of such forces acting and is incapable of predicting the uplift displacement. In this paper, the proposed method adds variables including the uplift displacement, , and settlements of backfill, , under the condition that the volume of an uplifted portion of a manhole is equal to a settled volume of a trench-backfill. To date, the method is verified through comparison with the results of 1-G and centrifuge model tests. A new safety factor, which takes into account the amount of manhole uplift and backfill settlement, is also derived.
