The selection of foundation type for photovoltaic (PV) panels depends on several factors, including soil type, geographical location, site topography, groundwater level, and soil corrosion potential. Common foundation solutions for ground-mounted PV panels include ballasted foundations, ground screws, helical piles, and, most frequently, driven steel micropiles. The current study focuses on optimizing the design of foundations using steel micropiles by leveraging Cone Penetration Test (CPT) results to enable more ...

The recycling of old extractive dumps as filler and aggregate in civil and road construction is considered a conventional recycling method. In contrast, the use of extractive waste as an admixture in cement or as a precursor additive in clinker manufacturing represents an upcycling approach. Regulation (EU) 2024/1252 has shifted the paradigm of waste upcycling by highlighting the dissipative loss of critical raw materials contained not only in extractive waste but also in other waste types when recycled without aw...

Pre-failed landslides occurring in quasi-homogeneous soils are difficult to be characterized from the standpoint of their partially formed failure surface geometry. The paper presents the combined geotechnical investigation methods (fully sampled boreholes with laboratory tests, in-situ dynamic probing and so on) giving a very accurate point-wise description of the soil, with geophysical methods (electric resistivity tomography пїЅ ERT, seismic refraction and multichannel analysis of surface waves пїЅ MASW) provid...
