Assessment of Soil Arching Factor for Retaining Wall Pile Foundations
Despite the prevalence of the soldier piles retaining wall systems as temporary and even permanent shoring systems along state highways, relatively little is known on the effect of the fore-slope bench width and the slope inclination on the arching capability factor used in design codes and standards. A review of literature indicated that no full-scale tests were conducted for soldier pile systems and only a few components have been modeled analytically, often using 2-D analyses that cannot capture the complex 3-D behavior of the arching behavior in active and passive regions of soldier pile retaining wall systems. To help address this gap in knowledge, an analytical research program is developed herein to assess the current design procedures on soldier pile walls and make recommendations for improvement, specifically with respect to 3-D effects of soil arching, fore-slope sloping ground, and bench width, based on a parametric study supported on advanced nonlinear finite element models of the soldier pile systems. Discussions on how to account for 3-D effects based on 2-D analyses and on how to account for bench width effects when classical soil theories are used in design are provided. Finally, a proposed experimental program is simulated using the modeling approaches developed in this study.
