Inclined backfill
WebIn this paper, a theoretical model is presented and applied to obtain and calculate the lateral pressures exerted on the filling barricade and to understand the effects of the filling process. It is found that the yield stress of cemented backfill increases with curing time and this relationship can be described as an increasing power function. WebFeb 19, 2024 · In the category of upper bound limit analysis theorem, a modified semi-analytical method for determining the seismic earth pressures of inclined unsaturated backfills is provided. Applicability and reliability of this method is varied through comparisons and the seismic responses of 3D inclined unsaturated backfills are studied.
