By the end of this section, students will have the ability to design and analyze shallow foundations using PLAXIS 3D under various loading conditions, including vertical, eccentric, inclined, and combined loads. They will learn to calculate the ultimate bearing capacity of square, circular, strip, and combined footings on different soil types such as sand, clay, layered soil, and rock. Additionally, students will explore the influence of key factors like water table fluctuations, foundation depth, and soil-structure interaction on foundation performance.This section also focuses on optimizing numerical simulations by using symmetrical quarter models, reducing mesh size, and improving analysis efficiency. Students will gain hands-on experience in simulating shallow foundation behavior under elastic, elasto-plastic, drained, and undrained conditions while comparing the accuracy of different soil constitutive models like Mohr-Coulomb and Hardening Soil. Advanced geotechnical challenges, including granular trenches, cavities, dewatering, and underground structures, will also be addressed.By integrating theoretical knowledge with practical applications, this section equips students with essential numerical modeling techniques for real-world geotechnical problem-solving. They will develop expertise in evaluating settlement and factor of safety under varying soil conditions and loading scenarios, ensuring precise and reliable foundation design. This knowledge enhances decision-making skills and prepares students to tackle complex geotechnical challenges with confidence.
