Abstract

Urban excavations are frequently performed using anchored retaining walls. Overall stability is an important stability verification in such walls and is significantly influenced by geometrical and mechanical characteristics of the wall, of the anchors and of the soil. In the present work, particular emphasis is given to the role of the embedded length in reducing the needed anchor length to ensure the overall stability, for the case of single anchored retaining walls. The need to reduce the anchor length can be justified by economical and technical reasons. The problem is analysed using classic limit equilibrium methods and finite element calculations.
