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…
What is a geotechnical study? The geotechnical study, or as it is also known, soil investigation, is the procedure by which you can find out the soil’s physical properties. It is usually used on construction sites to determine if the soil is safe for the construction that will be done. Without soil analysis, construction projects…
Stability analysis of embedded cantilever retaining walls in seismic area is generally carried out by calculating a factor of safety against a possible mechanism of collapse. However, a more rational approach consists in assessing the performance of the structure in terms of accumulated permanent displacement (Fig. 1). Indeed, this approach is required by many national…
The oedometric test The oedometric test is used to study the one-dimensional compressibility characteristics (zero lateral deformation) of a cohesive soil in the laboratory. The data obtained is of utmost importance for hypothesizing the behavior of a soil subjected to a change in stress state from the in situ state (e.g., oedometric stresses such as…
Extensively used at an international level, Slope stability analysis software – SLOPE is one of the most used software for slope stability verification of both loose and rocky soils, using the traditional methods of geotechnics (Limit Equilibrium), and the Discrete Element Method. Under seismic conditions, it is possible to choose either the pseudo static method…
In the proposed example is reported the piping verification of a channel section through the use of GeoStru software GFAS (Finite Element Analysis in Geotechnics). The geotechnical parameters used in the analyses and the geometries of the investigated sections refer to the Geological Report derived from in situ investigations. Cross section geometry The geometry of…
