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...
متن کاملSeismic Earth Pressure Development in Sheet Pile Retaining Walls: A Numerical Study
Abstract: The design of retaining walls requires the complete knowledge of the earth pressure distribution behind the wall. Due to the complex soil-structure effect, the estimation of earth pressure is not an easy task; even in the static case. The problem becomes even more complex for the dynamic (i.e., seismic) analysis and design of retaining walls. Several earth pressure models have been de...
متن کاملStudy of Bored Pile Retaining Wall Using Physical Modeling
Abstract—Excavation and retaining walls are of challenging issues in civil engineering. In this study, the behavior of one important type of supporting systems called Contiguous Bored Pile (CBP) retaining wall is investigated using a physical model. Besides, a comparison is made between two modes of free end piles (soft bed) and fixed end piles (stiff bed). Also a back calculation of effective ...
متن کاملDeep Pore Pressures and Seafloor Venting In
The pore pressures of the S, R, Q and P sands follow the hydrostatic gradient and are in pressure communication across the entire Auger basin, Gulf of Mexico. At the structural crests of these sands the pore pressures exceed the least principle stress; directly above the sand crests, are a series of mud volcanoes. Using 3-D seismic and pressure data we map the distribution of subsurface pressur...
متن کاملseismic 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...
