The case study discussed in this paper deals with the excavation of an excessively deep and long trench in a clay slope made at one edge of an urban connection road.

Abstract

The case study discussed in this paper deals with the excavation of an excessively deep and long trench in a clay slope made at one edge of an urban connection road. The subsequent failure of the top portion of the slope did not cause any human casualty but severe damage to a neighbouring retaining wall and to an adjacent building. The works aimed at the stabilization of the slope are suspected to have increased the damage to the foundation system of the building. The aim of this paper is that of showing that all the events could be foreseen just relying on the basic concepts of mechanics and on proper engineering practice. The causes for the landslide, and subsequent problems, are to be found in an excessive confidence in soil cohesion and in the application of standard engineering procedures in a non-standard case
