Analysis of Various Improvements in Cantilever Retaining Wall Using Geo 5 Software

Abstract

In hilly regions it is very important to build a retaining structures which with stand the lateral earth pressure exerted by water pressure, surcharge loads and self-weight of the wall. Retaining walls are built to withstand almost vertical (steeper than 70degrees) or vertical slopes of earth masses. In the past years, there has been rapid development of highways and unstability of retaining walls to cause embankment landslides has become common. We have discussed certain different materials which help in reducing the effective stress on the retaining wall such geofoam and soil mixture of shredded tires and controlled low strength materials. We have also studied what structural modifications can be made into the design of retaining walls so as to increase the stability of retaining walls. We have modified the basic retaining wall by providing a relief shelve and a shear key at various levels. In this project we have also studied the behavior of retaining walls under seismic conditions. This report summarizes various methods which we can use to increase the strength of a retaining wall. Analysis of different retaining walls is done on GEO 5 software.
