摘要：Abstract
The southern part of the Apulia region (the
Salento peninsula) has been the site of at least fifteen collapse
events due to sinkholes in the last twenty years. The
majority of these occurred in "soft" carbonate rocks (calcarenites).
Man–made and/or natural cavities are sometimes
assets of historical and archaeological significance.
This paper provides a methodology for the evaluation of
sinkhole hazard in "soft" carbonate rocks, combining seismic
and mine engineering methods.Acase study of a natural
cavity which is called Grotta delle Veneri is illustrated.
For this example the approach was: i) 2D and 3D seismic
methods to study the physical-mechanical characteristics
of the rock mass that constitutes the roof of the cave; and
ii) scaled span empirical analysis in order to evaluate the
instability of the crown pillar’s caves.
