Here's a brief overview: Soil Compressibility 1. *Definition*: Soil compressibility refers to the reduction in soil volume due to applied loads, causing settlement and deformation. 2. *Factors Affecting Compressibility*: Moisture content, soil type, density, and stress history. 3. *Compression Index (Cc)*: Measures soil compressibility, with higher values indicating greater compressibility. Geo-Wedges (Stability Analysis) 1. *Definition*: Geo-wedges are graphical methods for analyzing slope stability, considering soil strength and pore water pressure. 2. *Components*: Wedge geometry, soil properties, and external loads. ...
