Deep Excavations in Soft Ground

This lecture covers the control of the water table, embankment excavations, stability, and classification of excavations in soft ground. It discusses the types of walls used in deep excavations, the stability of embankment excavations, and the importance of capillary cohesion in soil. The instructor explains the concepts of slope stability, circular sliding, and the Bishop simplified method. The lecture also addresses the factors affecting the stability of excavations, such as soil density, slope angle, and safety factor. Various methods for analyzing slope stability and the importance of drainage in ensuring stability are highlighted. Additionally, the lecture touches on the significance of capillary bridges in soil cohesion and the challenges faced during embankment searches.
