3D Engineering Geological Modeling to Investigate a Liquefaction Site: An Example in Alluvial Holocene Sediments in the Po Plain, Italy
نویسندگان
چکیده
Liquefaction-induced surface manifestations are the result of a complex geological–geotechnical phenomenon, driven by several controlling factors. We propose multidisciplinary methodological approach, involving engineering geologists, geomorphologists, sedimentologists, and geotechnical engineers, to build 3D geological model for liquefaction assessment studies. The study area is Cavezzo (Po Plain, Italy), which municipality hit superficial during Emilia seismic crisis May–June 2012. site characterized Holocene alluvial sequence floodplain, fluvial channel, crevasse splay deposits prone liquefaction. integration different investigations, such as boreholes, CPTm, CPTu, laboratory tests, allowed us recognize potentially liquefiable lithological units, crucial hazard resulting reveals strict correlation co-seismic with buried silty sands sandy silts within shallow 10 m in channel setting, capped laterally confined clayey deposits.

Forest ecosystems play an important role for the conservation of biodiversity, and for the protection of ecological processes. The Po plain woodlands which once covered the whole Plain, today are reduced in isolated highly threatened remnants by modern intensive agriculture. These close to natural floodplain forests are one of the most scarce and endangered ecosystems in Europe. Saproxylic spec...

Hydraulic tomography is a recently developed aquifer characterization technique that involves the performance of a large number of short-term pumping tests, each of which stresses a different vertical interval in a well. Simultaneous analysis of drawdown measurements obtained from the entire set of tests provides the potential to estimate between-well hydraulic conductivity (K) variations at a ...
