Deep Foundation Design for Complex Soils

Why Deep Foundations Are Required In many projects, shallow foundations are sufficient to support the loads of a structure because the surface soils have adequate bearing capacity and settlement characteristics. However, in other cases, near-surface soils may be too weak, compressible, or variable to provide reliable support. This is particularly evident in areas with soft […]

Three-dimensional Bearing Capacity of Footings on Sand over Clay

Introduction The bearing capacity of soil is one of the most critical factors in foundation design, particularly where sand overlies clay. While dense sand offers relatively high load-bearing strength and effective drainage, underlying clay soils are often weaker, compressible, and more prone to long-term settlement. This layered interaction poses challenges for shallow foundations, where the […]
