Lateral Soil Pressure & Retaining Structures

Lecturer:  Saad-Eldin Elbedwihy, P.E.

Learning Objectives: Normally, Soil is the ultimate supporting material to all man made structures. On a transitional elevation changes (ramp like or hills) of slopes varying according to soil parameters and its own strength factors, soil can naturally adjust its own position, its particles may interact to get to a stable position. The health, safety, and welfare of the general public, and the value of the structure, become most critical.

(II). Qualitative understanding of the problem & the solutions

Loads acting on a retaining structure/wall, in general

Modes of failure

Types of lateral soil pressure, practical meaning and mathematical formulae

Types and effect(s) of surcharge

“AASHTO” design requirements & recommendations

Practical considerations

Practical approach to resolve real problems

(III). Numerical examples
