摘      要：The Torgiovannetto quarry(Assisi municipality,central Italy) is an example of a site where the natural equilibrium was altered by human activity,causing current slope instability phenomena which threaten two roadways important for the local *** quarry front,having a height of about 140 m,is affected by a 182,000 m3 rockslide developed in intensely fractured limestone and is too large to be *** 2003 some tension cracks were detected in the vegetated area above the quarry upper *** then on,several monitoring campaigns were carried out by means of different instrumentations(topographic total station,extensometers,inclinometers,ground-based interferometric radar,laser scanner and infrared thermal camera),allowing researchers to accurately define the landslide area and *** latter s major displacements are localized in the eastern *** deformational field appears to be related to the seasonal *** landslide hazard associated with the worst case scenario was evaluated in terms of magnitude,intensity and triggering *** the definition of the possible runout process the DAN 3D code was *** simulation results were used in order to design and construct a retaining ***,in order to preserve both the safety of the personnelinvolved in its realization and of the roadways users,an early warning system was *** early warning system is based on daily-averaged displacement velocity *** alarm level is reached if the prediction based on the methods of Saito(1969) and Fukuzono(1985) forecasts an imminent rupture.
