Introduction

Some types of civil works require containment certain land mass, to

resolve this situation is conducted called building retaining walls, these

structures have the function of containing this soil mass, but prior to

dosing the same walls, engineers must perform a series of studies that

reveal how works the side pressures from the soil mass, this lateral

efforts have been classified into three categories: at rest pressure, active

pressure,and passive pressure, the nature of this classification will look at

the theoretical section of this document.

Throughout the history of geotechnical, were two characters of great

importance that investigated the soil pressure conditions in a state of

plastic equilibrium Rankine (!"#$ and %oulomb (##&$, these scholars

proposed that mathematical e'pressions have enabled the calculation oflateral forces in active and passive condition, these mathematical

e'pressions differ with respect to a friction factor between the soil mass

and the containing structure.

To complement the process of building a wall of successful containment,

engineers must consider the types of failures that can occur in these

structures, for this should calculate a safety factor which must be within

the range set by building standards, this factor is a function of the lateral

forces of the soil mass and weight of the structure itself, the most

important types of fault are: overturn failure about its turn, sliding failurealong its base and failure load capacity of the base these fault conditions

will be discussed further in this document.
