“…The other factors that might in uence the parameters are micro-fractures and cementation. Minor amounts of clay minerals in sand or silt can increase the compressive strength to such an extent that the clay containing sediment has a higher strength than pure sand or silt [39]. In the current study, no clay content data was available and the mineralogy of the samples was not listed in the core logs or laboratory analyses.…”

“…The importance of clay mineralogy and the clay content as a control function of the physical properties such as density, Atterberg consistency limits and compressive strength of mudrocks were also emphasized by [38]. Carbonate content can also have a strong e ect on the strength and plasticity of hard soils-soft rocks [39]. Our study provides a fresh example of the fact that lithological variations only partly determine the strength parameters and cohesion, angle of friction can be highly variable and display major changes even when only a minor amount of clay is found in the sample [21].…”

Abstract:The paper presents the evaluation of engineering geological laboratory test results of core drillings along the new metro line (line 4) in Budapest by using a multivariate data analysis. A data set of 30 core drillings with a total coring length of over 1500 meters was studied. Of the eleven engineering geological parameters considered in this study, only the ve most reliable (void ratio, dry bulk density, angle of internal friction, cohesion and compressive strength) representing 1260 data points were used for multivariate (cluster and discriminant) analyses. To test the results of the cluster analysis discriminant analysis was used. The results suggest that the use of multivariate analyses allows the identi cation of di erent groups of sediments even when the data sets are overlapping and contain several uncertainties. The tests also prove that the use of these methods for seemingly very scattered parameters is crucial in obtaining reliable engineering geological data for design.

“…The engineering-geological map of the Western Thessaly basin was compiled by evaluating the above mentioned data. According to the international guidelines and recommendations, this map is characterized as a multipurpose, synoptic and large scale engineeringgeological map [2][3][4][5][6][7]44]. The map includes thirteen (13) engineering-geological units, based on their geological origin, relevant age, composition, physical state and geotechnical conditions ( Figure 3).…”

An engineering-geological map of the Western Thessaly basin has been compiled, providing a valuable guide to both urban planning and industrial development of the wider area. This map contributes significantly to the optimization of land use and improved planning of technical work. Additionally, the engineering-geological conditions of the formations encountered in the Western Thessaly basin are examined. The formations are grouped into thirteen (13) engineering-geological entities, with regard to their geotechnical behaviour. This entire study was based on both in situ investigations and geotechnical information extracted from 1,039 boreholes. Furthermore, a landslide inventory map of the Western Thessaly basin has been compiled. In addition, the surface subsidence ruptures, due to ground-water overexploitation, have been examined in the eastern part of the study area.

“…It comprises the most extensive smooth-relief area in the Greek peninsula, delimited to the North by the Hasia, Titaros and Olympus Mountains, to the East by Ossa and Pilio Mountains and the Aegean Sea, to the South by Orthrys Mountain and to the West by Pindos mountain range [9][10][11][12][13]. Internally, the Plain of Thessaly is divided by a low-lying hilly area, as the Western (Plain of TrikalaKarditsa) and the Eastern parts (Plain of Larisa).…”

Correlation between the structural pattern and the development of the hydrographic network in a portion of the Western Thessaly Basin (Greece)

Abstract:In the context of the present study the structural pattern in the Western Thessaly Basin (Greece) has been examined, based on structural data collected from the entire study area that were further correlated to the hydrographic network. The structural pattern of the area was revealed from tectonic analysis. Additionally, the topography, stratigraphy and sedimentology of the study area were taken into account. GIS techniques were used to map the spatial distribution of the geological and tectonic features on the topographic relief of the area. The oldest structures are contractional in nature, deformed by normal faulting related to the extensional episodes initiated in Serravallian times. It is inferred that the orientation of the stress field in the area has changed several times: the N-S stress field which was dominant during Late Serravallian times changed to NW-SE (MessinianZanclian) up to E-W in Zanclian and subsequently to roughly NNW-SSE (in late Piacencian). The NE-SW stress that was dominant in Pleistocene became N-S in later times. In addition, some changes in orientation are also indicated for the transitional periods of the pre-mentioned extensional episodes, possibly related to local events, or as a block-related deformation. The development of the 7 th order streams is probably related to the N-S extensional faulting initiated in Pliocene times, while the dominant direction of the 6 th , 5 th and 4 th order streams is possibly connected with the presence of the NNE-SSW and NW-SE extensional faults. Finally, the lower order streams are probably related to the most recent E-W striking normal faults.
