Liquefaction and earthquake Liquefaction is an extraordinarly complex and potentially destructive phenomenon that can occur during a seismic event of significant intensity. The accelerations generated by a seismic event result in an increase in the neutral pressure of the interstitial water contained in saturated sandy soil. Figure 1 – Comparison between stable soil on the…
Are you an architect looking to simplify the process of geotechnical calculation and analysis? Do you need reliable tools to ensure the safety and efficiency of your designs? Let me introduce you to GeoStru, a leader in the field of geotechnical engineering and specialized software. Geotechnical engineering is a fundamental component of modern architecture. A…
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.
Important news in the latest update of the GeoStru software Retaining walls – MDC, in fact, it is now possible to design and verify retaining walls of the gabion and block type. In this article, we will quickly look at how to set up a gabion and block wall. Premise on calculations in gabions and…
At 16:58 (Local Time) on 13 February 2023, a strong earthquake struck Romania. The epicenter near the city of Târgu Jiu, the capital of the district of Gorj, in the historical region of Oltenia has about 80 thousand inhabitants. The earthquake had a magnitude of 5.2 on the Richter scale and a depth of 10km.…
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…
In the design of road and rail embankments on fine-grained or very fine-grained soils, it is necessary to understand the settlements to overland the time. This is because, in the case of water infiltration, the drainage process takes place very slowly in the medium and long term. The problem is particularly felt in the sections…
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…
