Cardoso, António S., Nuno M. da Costa Guerra, Armando. N. Antão, and Manuel Matos Fernandes. "Limit analysis of anchored concrete soldier-pile walls in clay under vertical loading." Canadian Geotechnical Journal. 43 (2006): 516-530. AbstractWebsite

The vertical stability of anchored concrete soldier-pile walls is highly influenced by the complexity of the interaction between the different parts of the structure, i.e., wall, anchors, and supported soil mass. The problem is analyzed using upper bound limit analysis through published solutions and proposed closed-form equations. A comparison is made between these equations and numerical limit analyses. An estimate of the theoretical minimum pile resistance required to avoid excavation collapse is presented. Published finite element elastoplastic results are used for comparison.Key words: anchored retaining wall, concrete soldier-pile walls, vertical equilibrium, finite elements, limit analysis, soil-to-wall interface shear forces.
