Soil Mechanics

Every retaining wall, basement wall, sheet pile, and braced excavation must resist lateral earth pressure — the horizontal force a…

When a saturated clay layer is loaded — by a new building, embankment, or fill — the applied stress is…

When the soil near the surface is too weak to carry a structure’s load, engineers drive or bore piles —…

Safe bearing capacity (SBC) is the maximum pressure the soil beneath a foundation can carry safely — without shear failure…

Ask any engineering student what value to use for the specific gravity of soil solids, and the answer comes back…

When an engineer designs a retaining wall, one of the first things calculated is the lateral earth pressure pushing against…

If you’ve ever picked up a lump of wet clay and noticed how it stretches, cracks, or flows depending on…

Foundation settlement is the downward movement of a structure caused by deformation or compression of the soil beneath it. Every…

Soil compaction in civil engineering is the densification of soil by applying mechanical energy to reduce air voids between particles….
