The "Concepts and Tools in Embedded Retaining Systems" module provides a comprehensive exploration of key elements in designing and analyzing structures for soil retention. Beginning with the establishment of design parameters such as design situation, life, and geotechnical categorization, the module progresses to the determination of lateral earth pressures, tension cracks, groundwater pressures, and surcharges. It encompasses various analysis methods, emphasizing the selection of suitable wall types and limit state design principles. Practical aspects include the design of temporary support systems and numerical modeling. The module delves into the application of Indian and international codes, standards, and provisions, offering insights into code design for retaining structures and relevant standards for underground structures. Practical software tools such as Plaxis 2D, Wallap, Roc Lab, and RS2 are introduced to enhance understanding and application in real-world engineering scenarios.
