Abstract

This paper describes a simplified numerical procedure based on the beam on elasto-plastic foundation modeling for analyzing the response of construction sequence on tieback walls in decomposed granite soils (SP). The analytical method of the soil-wall interaction is developed by taking into account the soil spring (P-y curves) coupling effects based on the Vlasov model. A framework for determining the soil spring constants is proposed from laboratory model tests and numerical analyses. Through comparisons with case studies, it is found that the sequential behavior of tieback walls using coupling between soil springs agrees the general trend observed by small- and full-scale tests, and thus represents a significant improvement in the prediction of load-deflection relations of tieback walls.
