“…A comparison between multi-temporal TLS data has been demonstrated to be useful for monitoring slope displacements and deformation (Abellan et al 2011), to delineate their extent, to estimate the involved volume (Kuhn and Prüfer 2014) and to provide a general description of the ongoing processes (Pesci et al 2007). …”

Landslides of the lateral spreading type, involving brittle geological units overlying ductile terrains, are a common occurrence in the sandstone and limestone plateaux of the northern Apennines of Italy. The edges of these plateaux are often the location of rapid landslide phenomena, such as rock slides, rock falls and topples. In this paper we present a back-analysis of a recent landslide (February 2014), involving the north-eastern sector of the San Leo rock slab (northern Apennines, Emilia-Romagna Region) which is a representative example of this type of phenomena. The aquifer hosted in the fractured slab, due to its relatively higher secondary permeability in comparison to the lower clayey units leads to the development of perennial and ephemeral springs at the contact between the two units. The related piping erosion phenomena, together with slope processes in the clayshales have led to the progressive undermining of the slab, eventually predisposing large-scale landslides. Stability analyses were conducted coupling Terrestrial Laser Scanning (TLS) and Distinct Element Methods (DEMs). TLS point clouds were analyzed to determine the pre-and post-failure geometry, the extension of the detachment area and the joint network characteristics. The block dimensions in the landslide deposit were mapped and used to infer the spacing of the discontinuities for insertion into the numerical model. Threedimensional distinct element simulations were conducted, with and without undermining of the rock slab. The analyses allowed an assessment of the role of the undermining, together with the presence of an almost vertical joint set, striking sub-parallel to the cliff orientation, on the development of the slope instability processes. Based on the TLS and on the numerical simulation results, an interpretation of the landslide mechanism is proposed.

Abstract:The deformation of underground gateroads tends to be asymmetric and complex. Traditional instrumentation fails to accurately and conveniently monitor the full cross-sectional deformation of underground gateroads. Here, a full cross-sectional laser scanner was developed together with a visualization software package. The developed system used polar coordinate measuring method and the full cross-sectional measurement was realized by 360° rotation of laser sensor driven by an electrical motor. Later on, the potential impact of gateroad wall flatness, roughness and geometrical profile as well as coal dust environment on the performance of the developed laser scanner were evaluated. The studies show that a high-level flatness is favorable in application of the developed full cross-sectional deformation monitoring system. For a smooth surface of gateroad, the sensor cannot receive reflected light when the incidence angle of laser beam is large, causing data loss. Conversely, the roughness surface shows its priority as the diffuse reflection light can be received by the sensor. With regards to the coal dust in measurement environment, the fine particles of floating coal dust in the air can lead to the loss of measurement data to some certain due to scattering of laser beam.

In the course of field work based on geo log i cal and land slide map ping and spa tial anal y ses of map in for ma tion at least 2 types of land slides were iden ti fied. Type I: sim ple land slides de vel oped in ho mo ge neous and un dis turbed rocks, for in stance -loams, clays and sands. This type of land slide in cludes many ex am ples de vel oped mainly on the stretch (seg ment of the stud ied area) ap prox i mately be tween 132.25 and 133.50 km and 128.50 and 129.50 km of the Pol ish coast line. Type II: complex land slides in which the move ment and dis place ment of rock masses oc curs un der com plex geo log i cal and hydrogeological con di tions. The com plex fac tors are de ter mined by phe nom ena such as glaciotectonics, dis con ti nu ities of rock lay ers and thrust zones; the slip sur face oc curs at con sid er able depths, and some times sev eral slip sur faces can be distin guished. These land slide types are lo cated in the vi cin ity of Jastrzêbia Góra and Rozewie, near km 134 and 131.5. Pre diction of the for ma tion of this land slide types is dif fi cult. Even if long-term ob ser va tions are avail able, the mass move ment, vari able over time, is dif fi cult to in ter pret. It is clear that the changes are con tin u ous, but oc cur with vary ing in ten sity. Proper rec og ni tion of the types of mass move ment is cru cial to es tab lish ing the ap pro pri ate meth ods to pre vent their de vel op ment.
