Abstract

Retaining walls with broken sloped backfill (RWBSB) are popular in North America in transportation projects. AASHTO (AASHTO LRFD Bridge Design Specifications, Customary U.S. Units. American Associa-tion of State Highway and Transportation Officials, 2020) suggests a limit equilibrium analysis to calculate lateral earth pressure on RWBSB. In this paper, we used upper bound (UB) and lower bound (LB) finite element limit analysis (FELA) under plane strain conditions to calculate active and passive earth pressures on RWBSB. The accuracy of the adopted numerical method is first verified against some simple cases of active and passive earth pressures in the literature. Using this validated numerical approach, a parametric study is further performed to calculate active and passive earth pressures on RWBSB. The influence of various parameters including backfill friction angle, soil-wall friction angle, slope inclination angle, and height of the broken slope on the active and passive earth pressures are systematically investigated and discussed.
