In the design of retaining walls subjected to seismic loads, the pseudo-static method based
mainly on the Coulomb approach (equilibrium of forces) is widely used. However, this method does not
consider all the complex phenomena observed during the experimental tests, such as tension cracks, the
non-linearity of soil response, and the shape of failure surfaces. Therefore, researchers have long been
working to develop formulations that take these phenomena into account. This note presents a formulation
of the active dynamic thrust applied to a cantilever retaining wall supporting C-Φ soil, considering the
shape of the sliding surfaces in the active state. The equation of this formula is based on the pseudo-static
approach and considers the vertical and horizontal components of the seismic coefficient.
