... that the industry practice outlined in Ingram (2012) for the calculation of earth pressure due to restrained heave is inadequate. Soil–structure interaction effects need to be explicitly incorporated in the design method, to properly assess the effective heave pressure (EHP) acting on the structure due...

...David Perozzi; Alexander M. Puzrin Determining earth pressure-induced moments in the active limit state is critical for the safety assessment of retaining structures. While traditional design methods assume a Coulomb's resultant force acting at one-third of the wall height, the literature suggests...

...Fengwen Lai; Ningning Zhang; Songyu Liu; Dayu Yang Active earth pressure on retaining structures supporting a narrow column of soil cannot be properly analysed using Coulomb's theory. Finite-element limit analysis (FELA) shows that the soil forms multiple failure surfaces if the soil column...

...Chuhan Deng; Stuart K. Haigh A series of centrifuge tests was conducted to explore the deformation mechanisms and earth pressures mobilised in loose and dense sand for a complete set of passive movement modes of a rigid retaining wall: rotation about the top and base and translation. Sand...

Combining the altered vertical soil stresses with earth pressure coefficients depending only on the soil friction angle adequately bounds the horizontal stresses that develop in the soil. Fig. 3.

...Alexander M. Puzrin Inspired by two practical cases in Switzerland, the paper investigates a problem of elevated earth pressures downslope of existing landslides. This problem is relevant for both permanent landslides and one-time events, and of particular practical interest is the area...

..., equation (5) indicates that α is expected to increase, rather than decrease, with increasing sand density. The assignment of values for the magnitude of horizontal earth pressure at rest, which is relevant to many problems in geotechnical engineering, is often based upon the magnitude...

... the wall is moving towards the backfill, causing the retained soil to approach passive limit state conditions and the earth pressure distribution to be different from, and certainly larger than, the active limit value. However, based on the results from centrifuge tests on small-scale cantilever walls, Al...

... of a landslide, the existing classical earth pressure and landslide pressure solutions are not capable of describing the loads adequately. In this paper it is shown that accumulated loads acting on a building eventually lead first to a local limit state with failure in the vicinity of the building, followed...

... of an approximately rigid rotation around a point located close to the wall base, it is assumed that active and passive pressures are fully mobilised up to a certain depth from the excavation level. Below this depth, a simplified distribution of earth pressure is considered, with values that are not predetermined...

...B. Friedli; D. Hauswirth; A. M. Puzrin The problem of the limiting landslide pressure on an obstacle was first formulated in 1944 by Robert Haefeli of ETH Zurich, who recognised that the kinematics of the problem does not allow for classical active and passive earth pressure theories to be applied...
