According to the retaining wall that reinforced by extensible reinforcements such as geogrids and geotcxtiles, a new slice analysis methodology was developed to analyze its internal stability under horizontal and vertical seismic loads. The slide failure wedge of the reinforced retaning wall was divided into a number of soil slices parrallel to the reinforcements. Based on the single line shape assumption for the critical slip surface of the wall, the equilibrium equations for horizontal forces, vertical forces and moments of each soil slice were established. And then, the recurrence formulas ...
