How deep should the subsoil be investigated beneath...
Road and bridge construction is not just about asphalt and concrete – it’s primarily about solid foundations in the ground. In the latest issue of Autostrady magazine, Dr. Eng. Siergey Ihnatov addresses a key topic for engineers and designers: the required depth of subsoil investigation beneath embankments.
The article analyzes standards, engineering practices, and the relationship between the height and width of embankments and the scope of geotechnical investigations. It includes, among other things:
✅ a discussion of current standard requirements,
✅ results of FEM analyses and practical calculations,
✅ proposals for optimizing the scope of investigations for various terrain conditions.
It’s a must-read for professionals involved in the design and implementation of road infrastructure projects who aim to combine efficient investigation methods with structural safety.
