Why do Geo-technical engineers need to understand strees in rocks?

Geotechnical engineers need to understand stress in rocks to assess the stability and integrity of soil and rock formations for construction projects. This knowledge is crucial for predicting how these materials will respond to applied loads, which affects the design of foundations, slopes, and retaining structures. Understanding rock stress also helps engineers identify potential failure mechanisms and ensure safety and durability in engineering designs. Additionally, it aids in evaluating the suitability of sites for various projects, minimizing risks associated with ground movement and deformation.
