Evaluation of the effect of lateral soil pressure on cantilever retaining wall with soil type variation

Abstract

Retaining wall is defined as a structure with a main purpose to prevent lateral movement, retain earth or water and may role to support vertical loads. There are several types of retaining wall and the most common types used are gravity wall, cantilever wall, counterfort walls and buttressed wall. Therefore, a few components need to be used in order to get the objective. As a result, this system can be used for the design of a cantilever retaining wall. Moreover, it saves time in the design with sufficient layout detail of the cantilever retaining wall. Design of cantilever retaining walls involves stability checks for overturning, sliding and bearing. A trial section is assumed and calculations are made for the stability checks. The important parameters involved are unit weight of backfill soil, stem height and concrete type. The base length and it components namely toe land heel lengths, and base thickness are highly dependent upon these factors and vary sharply with stem height. The trial section geometry for a given wall height, soil data and strength of concrete can be examine from these charts and final section profile may be determined within a minimum time. The charts have been prepared for a wide range of values of soil unit weight, moment.
