The permeability test in the oedometer cell is aimed at determining the coefficient of permeability (K) through direct measurement under variable hydraulic loading during the oedometric test. This type of test can be performed on soil samples primarily composed of silts and clays, whose permeability is greater than 10^-6 to 10^-7 m/s. Advanced configuration of…
BIM for Geotechnics and Geology: The GeoStru team is working at full pace to provide customers with the best solutions in Building Information Modeling (BIM). BIM has revolutionized the way architects and engineers work, and it also offers significant advantages in the field of geotechnics and geology. Work Methodology Those who use GeoStru software know…
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…
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…
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 collapse of retaining walls may result from several factors, including: Soil instability (GEO): If the soil surrounding the wall is unstable, for example, due to telluric movements, accumulation of water, erosion, etc. Structural settlements (STR): If the wall has been improperly designed or built, for example with inadequate structural stability or poor quality materials,…
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…
The EN Eurocodes apply to the structural design of buildings and other civil engineering works including, geotechnical aspects, structural fire design and situations including earthquakes, execution and temporary structures. For the design of special construction works (e.g. nuclear installations, dams, etc) other provisions than those in the EN Eurocodes might be necessary. It is basically used in 27…
