“…However, in the severely shaken areas of some recent major earthquakes good performance of reinforced soil slopes and walls were reported (Frankenberger et al, 1996;White and Holtz, 1997;Sandri, 1998;Tatsuoka et al, 1998). Good performance, in terms of a high ductility, of geosynthetic-reinforced slopes and walls against seismic loading has also been identified in physical model tests (Murata et al, 1994;Koseki et al, 1998;ElEmam andBathurst, 2005, 2007;Krishna and Latha, 2007;Huang and Luo, 2010), and in analytical studies (Bathurst and Hatami, 1998;Carotti and Rimoldi, 1998;Nouri et al, 2006;Choudhury et al, 2007;Fakharian and Attar, 2007;Narasimha Reddy et al, 2009;Leshchinsky et al, 2009). To take into account the ductile behavior of reinforced slopes in displacement-based seismic designs of geosynthetic-reinforced slopes, seismic displacement evaluations are necessary.…”

“…Using the limit equilibrium method, this analysis evaluated the dynamic thrust on retaining walls with a limited heel length. Huang [7] [8] conducted plane-strain model experiments to examine foundation settlement and deformation. They investigated the impact of cantilever soil retaining walls and geosynthetic-reinforced soil retaining walls with extended heels.…”

To enhance the resistance against sliding and overturning in a cantilever retaining wall, the study introduces a heel plate at the base of the wall’s backside. This heel plate is designed to work with the wall's combined weight and the soil fill's weight placed on the heel plate. These components work together to mitigate the lateral forces produced by the soil fill. The objective is to efficiently and cost-effectively mitigate the seismic forces by integrating a cantilever retaining wall with a heel plate and pre-stressed rope, capitalising on the favourable seismic response characteristics. The study used the kinematical approach based on the upper bound theorem to examine the system's failure mechanism and critical yield acceleration coefficient involving a retaining wall, ropes, and soil. This framework identified two distinct failure modes: the long-heel baseplate failure mode and the short-heel baseplate failure mode. These failure modes were distinguished based on the second and third conditions for generating slip surfaces in the analysis. Assuming that the sliding surface of the backfill follows a straight line, this study applies the Mohr-Coulomb failure criterion to establish critical state equations of pre-stressed ropes in a retaining wall with a heel, considering two distinct failure modes. Seismic yield acceleration coefficients are derived for each failure mode. Utilising the extremum principle, the study offers an optimal solution, including determining the critical yield acceleration coefficient and the associated inclination angle of the backfill sliding surface.

This paper presents a simple method to evaluate the seismic stability of Lshape retaining walls in the framework of the kinematical approach of upper bound theorem. It can predict the positions of two slip surfaces once the seismic acceleration threshold for slide is exceeded. Based on the wall-soil system collapse mechanism, the equation for expressing critical limit-equilibrium state was employed to define yield acceleration factor which contains two variables. Case study and comparative analysis show that: (1) critical yield acceleration factor is smaller than the M-O formula and NSPPS method; (2) the angle between the two surfaces equals to 90 o -φ.
