Distribution of lateral active earth pressure on a rigid retaining wall under various motion modes
The design of retaining walls depends on the magnitude of active pressure exerted from the backfill. Therefore, estimating the scale of this pressure is a fundamental factor in the design. In this study, to assess the active earth pressure, a rigid retaining wall was built capable of translating and/or rotating with adjustable speed. Further, several physical tests were conducte...
متن کاملEvaluation of Seismic Active Earth Pressure Using Horizontal Slice Method and Log-spiral Failure Surface
Evaluation of active earth pressure in seismic condition is one of the important problems of geotechnical earthquake engineering. In this study the static and seismic active earth pressure exerted by a homogeneous backfill behind a rigid retaining wall is evaluated using Horizontal Slice Method (HSM). Both cohesionless and cohesive soils are considered using c- soil in the formulation. The fai...
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...
متن کاملEstimation of active earth pressure against rigid retaining walls considering arching effects
It is known that the distribution of active earth pressure against a translating rigid wall is not triangular but nonlinear, owing to arching effects in the backfill. In the present paper, a new formulation is proposed for calculating the active earth pressure on a rigid retaining wall undergoing horizontal translation. It takes into account the arching effects that occur in the backfill (or re...
متن کاملOPTIMAL DESIGN OF CANTILEVER RETAINING WALL USING DIFFERENTIAL EVOLUTION ALGORITHM
Optimal design of cantilever reinforced concrete retaining wall can lead considerable cost saving if its involvement in hill road formation and railway line formation is significant. A study of weight reduction optimization of reinforced cantilever retaining wall subjected to a sloped backfill using Differential Evolution Algorithm (DEA) is carried out in the present research. The r...
