Terzaghi-Wegman Effect

The Terzaghi-Wegman Effect describes how properly designed underground support systems, like retaining walls or pilings, can become less effective over time if they don't account for soil settlement and movement. As the ground shifts or settles, these supports might lose their stability or strength, leading to potential structural failure. Essentially, it highlights the importance of considering long-term soil behavior and deformation when designing underground structures, ensuring they remain safe and functional as the environment changes over time.
