Horizontal slice method of analysis

Development of Horizontal Slice Method for seismic stability analysis of reinforced slopes and walls

“…To overcome this problem, the idea of using horizontal slices was proposed by Lo and Xu (1992). Independently, Shahgholi et al (2001) employed the concept of horizontal slices within the framework of a pseudo-static method to evaluate the seismic stability of reinforced soil walls. The advantages of the approach used by Shahgholi et al (2001) include simplification of the analytical procedures and less numerical effort.…”

The advantages of the approach used by Shahgholi et al (2001) include simplification of the analytical procedures and less numerical effort. In this approach, the sliding mass is divided into several horizontal slices, which have rigid-plastic behavior, and the seismic inertia force is considered as pseudo-static force acting at the center of gravity of each slice.…”

“…In addition to the formulation proposed by Shahgholi et al (2001), new formulations for the HSM are introduced in the paper.…”

“…This first simple formulation, proposed by Shahgholi et al (2001) satisfies the following equilibrium equations: Table 1 List of unknowns and equations in two simple formulations (Shahgholi et al, 2001;Fakher et al, 2002) Unknowns…”

“…The development of a new limit equilibrium method of analysis for reinforced soil structures, identified as the Horizontal Slice Method (HSM), is presented in this paper. Shahgholi et al (2001) employed the method to analyze the seismic stability of reinforced soil walls. The present paper extends the latter work by developing a number of formulations, including a fully rigorous method of analysis.…”
