Plaxis is a software program used for geotechnical engineering and soil mechanics. It helps engineers analyze and design structures that interact with soil, such as foundations, tunnels, and embankments. By simulating how soil behaves under various conditions, Plaxis allows for better decision-making in construction projects. The software employs advanced numerical methods, particularly the finite element method, to model complex soil-structure interactions. This capability makes Plaxis a valuable tool for assessing stability, settlement, and other critical factors in engineering projects, ensuring safety and efficiency in construction practices.
