Finite Element Analysis of Earth Pressures for Narrow Retaining Walls

High traffic demands have led to widening of existing highways to accommodate increased traffic volume. However, due to the high cost of additional right-of-way and limited space available at job sites, construction of earth retaining walls is often done under a constrained space. This leads to retaining walls that are narrower than in design guidelines. This type of walls is referred as “Narro...

seismic analysis of lateral earth pressure and retaining walls

eart pressure problems are encountered in retaining walls, bulkheads, sheeting and bracing in cuts,culverts, tunnels, and cofferdams. in many cases, the lateral pressure is determined by use of classical earth pressure theories, such as coulomb's, where the equilibrium conditions of a failure wedge of soil is considered. excessive dynamic lateral earth pressure on retaining structures resu...
