Analysis of Tieback Soldier Pile Walls Using Numerical Iteration Method
Publication: ASCE Inspire 2023
ABSTRACT
In this study, a numerical iteration method is proposed to analyze the behavior of tieback soldier pile walls sustaining complex external loads. The proposed iteration method integrates the analysis features of the common engineering analysis software LPILE and SAP2000, which is a refined 2D analysis approach and saves the effort of performing the complicated 3D finite element analysis or the cost of purchasing costly advanced analysis tools. Based on the case study on the soldier pile tieback retaining wall from the VDOT I-66 Expressway project, it is observed that the proposed numerical analysis method provides accurate predictions of the deflection, shear, and bending moment results for the selected tieback soldier pile wall, and the iteration process converges quickly. This proposed numerical iteration method is also expected to be applicable for modeling soil-structure interactions of piles and shafts for integral-abutment bridges, long-span bridge piers, and other complex civil infrastructure, etc.
