Abstract

© Springer Nature Switzerland AG 2018. A set of analytical solutions achieved by the upper bound theorem of limit analysis and the pseudo-static approach is presented for the assessment of the stability of homogeneous c, ϕ slopes manifesting vertical cracks and subject to seismic action. Rotational failure mechanisms are considered for slopes with cracks of known or unknown depth and location. Charts providing the stability factor for fissured slopes subject to both horizontal and vertical accelerations for any combination of c, ϕ and slope inclination are provided. Yield seismic coefficients are also provided. Finally, Newmark’s method [1] was employed to assess the effect of cracks on earthquake induced displacements.
