Small-Strain Stiffness Values for a Reconstituted Soil from Southern Italy
No full textIn numerical modelling of soil response it is often required to define an accurate value for the stiffness at small strains (G0). Such values are usually obtained from tables or charts available in the literature, rather than being directly measured in tests. These will however be sufficiently accurate only if a similar soil has already been studied and described. In the present paper, the results of a series of laboratory tests conducted on a soil from southern Italy are reported. In these tests, a well-established empirical relationship linking small-strain stiffness values to state parameters was calibrated, allowing the determination of accurate G0 values for the specific soil, and contributing to the collection of data in the literature. The bender element technique, in conjunction with standard triaxial testing on reconstituted soil samples, was employed. A series of isotropic compression tests was used for the calibration, and the resulting power law was then checked through shear testing. The proposed equation compares well with results reported in the literature for different types of soils. On approaching failure a change in behaviour is evident; this is in accordance with observations already reported in the literature for a variety of soils and is subject to several interpretations, but does not substantially interfere with the general validity of the proposed correlation, which can therefore be adopted as a useful empirical equation for determining G0 values for this soil
Ground investigation: a tool for landslide risk mitigation of infrastructures
Full text linkRecent monitoring experiences for bridges in Central and South Italy have shown that it is not common for bridges to be directly damaged by landslides phenomena in their vicinities, either because their siting was very carefully selected at the origin or because appropriate protection measures have been taken to reduce geological risk to acceptable levels. In the first case, periodic visual inspections of the manufacts may suffice to monitor possible consequences of ground instability phenomena, but in the second case monitoring of the infrastructure and of the ground is the only possible tool to evaluate the existence of a landslide-structure interaction which can influence its performance and safety. Ground investigation is a fundamental activity for landslide monitoring and analysis, and this is specifically true when a landslide-infrastructure interaction problem needs to be investigated and assessed. By discussing the results from case studies recently inspected, this paper shows how the knowledge of the physical processes and the monitoring of selected parameters are the first irreplaceable tools to mitigate risks associated with instability phenomena interacting with sensitive infrastructures
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
