Résumé

The ground movements related to the presence of
old underground cavities are often damaging to structures
and infrastructures. Considering these ground movements
in calculations will prevent considerable human loss and
material damage. Many areas, both in Algeria and in
abroad, are prone to instability caused by ground rupture
and the phenomenon of sinkhole progression. The
objectives of this work are first to numerically simulate
the process of cavity collapse and second to analyze the
impact of cavity properties on structure stability. A finite
element model was established to analyze the influence
of several cavity parameters (dimensions, volume, and
spacing). Validation of the model relied on comparing
numerical results with experimental data from scientific
research, as well as those from analytical approaches.
Adequate correlation was achieved. The study allowed
deriving mathematical equations relating to several
parameters, including cavity dimensions and position
in the soil, soil characteristics, and footing width. These
results will be considered to reduce the risk of surface
structure instability.
