A tunnel is a horizontal or slightly inclined underground passage that runs through rock or unconsolidated materials and remains open at both ends. Commonly circular, semicircular, or horseshoe-shaped, tunnels serve various purposes such as water conveyance,...
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...
Folds are significant geological structures formed when rock layers undergo compression, resulting in bending without fracturing. They are commonly observed in deformed sedimentary, metamorphic, and even igneous rocks. Understanding the different types of folds and...
Types of Bridges: There are five major types of bridges, namely Girder or Beam Bridge, Cantilever Bridge, Arch Bridge, Suspension Bridge, and Cable-Stayed Bridge. The magnitude of the load of the bridge and the forces acting on the support system considered in the...
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...
Grouting plays a crucial role in geotechnical engineering by improving the strength, stability, and impermeability of soil and rock foundations. Engineers inject a fluid-like material into voids, cracks, or porous zones to seal, consolidate, or reinforce the ground....
