Geological-evolutionary model of a gravity-induced slope deformation in the carbonate Central Apennines (Italy), 2004, Martino S. , Prestininzi A. , Mugnozza G. S. ,
This paper discusses the findings from a study conducted on gravity-induced deformations occurring along the SW slope of Mount Nuria linking the village of Pendenza (Rieti, Italy) to the area of San Vittorino, in the alluvial plain of the Velino river, where important infrastructures are present. The dominantly carbonate composition of the rocks outcropping along the slope, the occurrence of a main spring fed by a regional karst aquifer and the interaction of gravity-induced deformations with buildings and infrastructures resting on the slope or located at its base make the investigated case extremely interesting and reflective of phenomena that are common in similar geological-hydrogeological conditions. Insights from this case and their use for the construction of a 'geological-evolutionary model' shed more light on the complex interactions existing between jointed carbonate rocks, seepage, karst dissolution, genesis of gravity-induced deformations and their evolution in space and time, through the analysis of stress-strain conditions within the slope. According to the selected methodological approach, data from detailed geological, geomorphological and geomechanical surveys were integrated with those from laboratory tests and from a complex slope monitoring system. From the results of the study it was possible to: i) refer the investigated phenomena to gravity-induced deformations on the slope scale; ii) build a representative 'geological-evolutionary model' and iii) develop an analytical approach to assess the hazard represented by these deformations for local buildings and infrastructures. The identification of different hazard conditions can help define the type and value of possible mitigation efforts. The investigated case also provided inputs for testing new approaches to the geomechanical characterization of rock masses, to the description of their jointing and to the correlation of their main discontinuities with tectonic and gravity-induced elements

From the geological to the numerical model in the analysis of gravity-induced slope deformations: An example from the Central Apennines (Italy), 2005, Maffei A. , Martino S. , Prestininzi A. ,
This paper presents the findings from a study on gravity-induced slope deformations along the northern slope of Mt. Nuria (Rieti-Italy). The slope extends from the village of Pendenza to the San Vittorino plain and hosts the Peschiera River springs, i.e. the most important springs of the Central Apennines (average discharge: about 18 m(3)/s). Detailed geological-geomorphological and geomechanical surveys, supported by a site stress-strain monitoring system and laboratory tests, led us to define the main evolutionary features of the studied phenomena. Based on the collected data, a 'geological-evolutionary model' was developed with a view to identifying a spatio-temporal correlation between relief forms, jointing of the rock mass and its stress conditions. The geological-evolutionary model was expected to improve numerical simulations and to test our assumptions. The numerical model also allowed us to simulate changes in the stress-strain conditions of the rock mass and correlate them with jointing, seepage, as well as with site-detected and site-monitored forms and deformations. In particular, significant relations between seepage, tensile stresses within the rock mass, karst solution and collapse of cavities were identified. (c) 2005 Elsevier B.V. All rights reserved

Structurally complex reservoirs: an introduction, 2007, Jolley S. J. , Barr D. , Walsh J. J. , Knipe R. J.

Structurally complex reservoirs form a distinct class of reservoir, in which fault arrays  and fracture networks, in particular, exert an over-riding control on petroleum trapping and production  behaviour. With modern exploration and production portfolios commonly held in geologically  complex settings, there is an increasing technical challenge to find new prospects and to  extract remaining hydrocarbons from these more structurally complex reservoirs. Improved  analytical and modelling techniques will enhance our ability to locate connected hydrocarbon  volumes and unswept sections of reservoir, and thus help optimize field development, production  rates and ultimate recovery. This volume reviews our current understanding and ability to model the  complex distribution and behaviour of fault and fracture networks, highlighting their fluid compartmentalizing  effects and storage-transmissivity characteristics, and outlining approaches for predicting  the dynamic fluid flow and geomechanical behaviour of structurally complex reservoirs.  This introductory paper provides an overview of the research status on structurally complex reservoirs  and aims to create a context for the collection of papers presented in this volume and, in doing  so, an entry point for the reader into the subject. We have focused on the recent progress and outstanding  issues in the areas of: (i) structural complexity and fault geometry; (ii) the detection and  prediction of faults and fractures; (iii) the compartmentalizing effects of fault systems and complex  siliciclastic reservoirs; and (iv) the critical controls that affect fractured reservoirs.


The authors have founded a new hypothesis that relates various karsts’ genesis, including hydrothermal-karstic ore deposits, and evolution of rock masses in the areas of endogenous ring structures. The hypothesis is backed by the fact that karstic manifestations stick to the ring morpho-structures. The presented substantiation grows strong with the physical and numerical modeling of the kasrt formation mechanics and comparison of the modeling results and field data.

On the applicability of geomechanical models for carbonate rock masses interested by karst processes, 2015,

Rock mass classification and geomechanical models have a particular importance for carbonate rocks, due to their peculiar fabric, variability of the main features, and scarce availability of experimental data. Carbonates are particularly sensitive to syn-depositional and post-depositional diagenesis, including dissolution and karstification processes, cementation, recrystallisation, dolomitisation and replacement by other minerals. At the same time, as most of sedimentary rocks, they are typically stratified, laminated, folded, faulted and fractured. The strength and deformability of carbonate rock masses are, therefore, significantly affected by the discontinuities, as well as by their pattern and orientation with respect to the in situ stresses. Further, discontinuities generally cause a distribution of stresses in the rock mass remarkably different from those determined by the classical elastic or elasto-plastic theories for homogeneous continua. Goal of this work is the description of the difficulties in elaborating geomechanical models to depict the stress–strain behavior of karstified carbonate rock masses. Due to such difficulties, a high degree of uncertainty is also present in the selection of the most proper approach, the discontinuum one or the equivalent continuum, and in the numerical model to be used within a specific engineering application as well. The high uncertainty might cause wrong assessments as concerns the geological hazards, the design costs, and the most proper remediation works. Even though recent developments in the application of numerical modeling methods allow to simulate quite well several types of jointed rock masses, as concerns carbonate rock masses many problems in representing their complex geometry in the simulation models still remain, due to peculiarity of the structural elements, and the presence of karst features. In the common practice, the improper use of the geomechanical models comes from a superficial geological study, or from the lack of reliable geological and structural data that, as a consequence, bring to erroneous evaluations of the influence of the geological-structural features on the in situ stress state and the stress–strain rock mass behavior.
