Discontinuity (geotechnical engineering)

In geotechnical engineering, "discontinuity" refers to a break or change in the continuity of a geological material, which can significantly influence its mechanical behavior and stability. Discontinuities can manifest in various forms, including: 1. **Cracks and Fractures**: Natural or induced breaks in rock or soil that can affect strength, permeability, and stability. 2. **Foliation**: Layers within metamorphic rocks that create planes of weakness.
