Primary Consolidation - Pore Pressure Dissipation - Delayed Settlements
This lecture covers the primary consolidation process in shallow foundations, focusing on the dissipation of excess pore pressure due to sudden loading and the subsequent delayed settlements. It discusses the use of various methods such as separation of variables and Fourier series for spatial variation, and exponential decay for temporal variation. The lecture also explores the calculation of consolidation settlements associated with different soil layers and the time required for dissipation of excess pore pressure. Examples and sensitivity analyses are provided to illustrate the concepts.
