Abstract
An analytical method based on the kinematic limit approach is presented for stability analysis of nailed soil slopes. Earthquake effects were considered in an approximate manner in terms of seismic coefficient-dependent horizontal forces. Two kinds of failure surfaces, a planar failure surface and a circular failure surface, were considered in this study. The proposed method can be viewed as an extension of the method of slices, but it provides a more accurate treatment of forces because they are represented in an integral form. The factor of safety and nail forces obtained by the proposed method were found to be in good agreement with the published results for an 8 m high vertical soil-nailed wall.
