Stress monitoring for safe tunnels and underground structures

In geotechnics, understanding the interaction between a structure and the surrounding ground is particularly important, as these relationships determine the safety and durability of underground projects. Systematic monitoring of stresses and pressures allows engineers to better anticipate potential risks, optimize construction processes, and minimize the likelihood of failures. With modern measurement solutions, real-time data becomes the foundation for making quick and accurate decisions, ensuring not only safety but also cost savings in infrastructure maintenance.
