Joints are natural cracks or fractures in rocks that form when stress exceeds the rock’s strength. Unlike faults, they show little or no movement along the fracture. Joints typically appear in sets with regular patterns and result from factors like rock type, stress...

The fault zone lying under gravity dams is composed of weak gouge materials with a low modulus of elasticity as compared to sound rocks, and hence is more deformable. The pressure of a fault zone induces more stress in a foundation than a normal foundation. A fault...
