ABSTRACT
The paper deals with flexible vertical walls embedded in soils which are stiffened by a horizontal cantilever platform. A special role is played by this horizontal structural member that reduces bending moments. This concept can be – to a certain extend – an alternative for expensive soil anchors. Such technical solutions are useful for long linear excavations (subways, highways, tunnels etc.) and also as single piles. Although limited to linearly deformable subsoil models – the simplest Euler-Bernoulli beams on the Winkler subsoil – the presented analytical solutions yield a prediction of the wall behaviour (displacements, internal forces), as well as can initiate parametric studies, sensitivity analysis and optimization. The obtained results make the design process more reliable and the use of retaining structures more environment-friendly.
