Abstract

The effects of a counterweight applied on the foundation slab of a leaning tower resting on deformable soils are analysed. The analysis is carried out on the base of a visco-elasto-plastic constitutive model, representing the mechanical behaviour of the soil (S) - foundation (F) geotechnical system, under loads whose intensity varies according to the tilting of the tower. The concept of admissible counterweight is first developed. The immediate effects of an admissible counterweight, and above all the elastic tilt reduction of the tower, are then determined as a function of the geometry of the tower and of its foundation, of the characteristics - weight and eccentrity - of the counterweight as well as of the current yielding level
