Application of static penetrometric tests in stratigraphic profile reconstruction Diego Lo Presti,* Claudia Meisina,** Nunziante Squeglia* Cone penetration tests are a well-established in situ test methods for site characterization. Their widespread use for subsurface explorations is due to their reliability, speed, economy and to the fact that they supply continuous records with depths of soil…
Indagini geognostiche, prove di laboratorio e risultati della relazione geologica: tutto quello che occorre sapere grazie alla utile guida geotecnica dei geologi del Lazio Per la progettazione accurata di un’opera, è essenziale condurre un approfondito studio del sottosuolo al fine di ottimizzare le risorse economiche in relazione alle prestazioni richieste. Il Collegio dei Geologi della…
Integrare il BIM nella Geotecnica e nella Geologia. Come definito dal NIBS (National Institute of Building Sciences), il Building Information Modeling è “una rappresentazione digitale delle caratteristiche fisiche e funzionali di una struttura, una risorsa di conoscenza condivisa di informazioni che costituisce una base affidabile per qualsiasi decisione lungo il suo ciclo di vita, dalla…
The Cam-Clay constitutive model is one of the most widely used mathematical representations to describe the mechanical behavior of undrained clayey soils. The model is named after A.W. Skempton and R.V. Whitman, who developed it in the 1960s. The Cam-Clay model is based on the idea that the behavior of undrained clayey soil is governed…
Dynamic characterization is a crucial step in designing earthquake-resistant structures. Non-destructive geophysical techniques like MASW are used to predict the shear wave velocity and provide valuable information for site characterization, ground response analysis, and micro zonation mapping. Studies have shown that NEHRP, IBC, and NTC2018 provisions can be used to classify soil profiles based on their shear wave velocities.
The piezometer What is a piezometer? The piezometer is an instrument for measuring the level of the water table and/or the interstitial pressures. This instrumentation is installed in the probing hole and performed with continuous core drilling or core destruction. Types of piezometer There are different types of piezometers adopted in low to the hydrogeological…
As in accordance with Eurocode 7 Part 1, the hen prediction of geotechnical behavior is difficult, so it may be appropriate to apply the approach known as the “observational method,” in which the design is reviewed during construction. This method is applied by following this procedure: limits of acceptability of the values of certain quantities…
