Prediction of Vertical Earth Loads on Rigid Pipes

Abstract

Standards are available to estimate the vertical earth loads induced on pier or pile‐supported rigid pipes subjected to cohesionless settling backfill. There is no apparent direct field evidence to support existing design procedures. Therefore, a literature review was made to determine whether alternative methods existed. This review indicated that many other methods do exist for cases where the fill either settles relative to a fixed foundation (or pipe) or the foundation is subjected to uplift forces. It is concluded that existing standards consistently underestimate the vertical earth loads.
