ANALYSIS OF RETAINING WALL FOR STATIC AND DYNAMIC CONDITION BY USING GEO-5 SOFTWARE

Abstract

A wall which is formed for opposing the horizontal physical force of earth becomes famous in the form of wall. This force is exerted because the soil repose angle exceeds due to the required modifications in ground height. Ahead of constructing this wall, means in its designing phase, it becomes essential to identify and balance the tendency of the retained material to lower inclination because of gravity. This force is entirely depends upon the angle of internal friction (ø) and the bonding power of the retained material. In addition it also depends, how much and in which direction retaining structure moves. Objective of this research is to analysis of gravity wall and cantilever retaining wall for varying terrains, soil condition and water table. Comparative analysis between classical and numerical approach (FEM). And also find out the most suitable retaining wall for different soil condition .Effect of dynamic loading resulted from earthquake of different soil condition, terrains and water table condition to be determined for gravity and cantilever walls. In thesis work two methodologies are used which is classical approach and numerical approach, Coulomb’s, method are used for active and passive condition &MononobeOkobe method is used for earthquake (dynamic) condition and Bishop’s method is used for slope stability, all methods are predicted by using of GEO 5 software. On the basis of present study following conclusions may be drawn that the factor of safety is decreasing with increase in slope angle. Force and moment are increasing with increasing in slope angle.The comparative study of finite element method and classical method as indicated that finite element approach is more near to the realistic condition and it evaluate the other parameter like stress intensity, shear strain deformation and FEM is also better due to in classical approach more assumption will be required, but in finite element method is that no assumption needs to be made in advance about the shape or location of the failure surface, slice side forces and their directions.
