TL;DR: In this paper, a simple-to-use method is proposed for the design of embedded cantilever retaining walls in cohesionless soils under static and seismic conditions, taking into account the displacement pattern generally exhibited by this type of structure.
Abstract: A simple-to-use method is proposed for the design of embedded cantilever retaining walls in cohesionless soils under static and seismic conditions. Taking into account the displacement pattern generally exhibited by this type of structure, which consists of an approximately rigid rotation around a point located close to the wall base, it is assumed that active and passive pressures are fully mobilised up to a certain depth from the excavation level. Below this depth, a simplified distribution of earth pressure is considered, with values that are not predetermined by limit state. Analytical expressions are provided to calculate readily the net pressures acting on the wall and the associated internal forces arising in the structure. Comparisons are made with numerical and experimental results concerning embedded cantilever retaining walls under static and seismic conditions. In all the cases considered, a fairly good agreement is found between these results and those predicted by the proposed method. Some a...

TL;DR: In this paper, a nonlinear method for seismic soil-pile-structure interaction is presented, which includes a consistent approach to determine seismic p-y relationships and a liquefaction model that is suited to pore pressure evaluation for earthquake-type irregular loadings.
Abstract: A nonlinear method for seismic soil-pile-structure interaction is presented. Primary features of the proposed method include a consistent approach to determine seismic p-y relationships and a liquefaction model that is suited to pore pressure evaluation for earthquake-type irregular loadings. The seismic- p-y relationships are determined from nonlinear stress-strain relations of soils, and include soil nonlinearity as well as pore pressure buildup effects around a pile. The performance and validity of the method were evaluated through an analysis of shaking table test on model soil-pile-structure systems. Using the proposed method, seismic response characteristics of an idealized offshore pile-supported structure at a sand site were analyzed. Results indicated that liquefaction as well as pore pressure bulidup around a pile can have a large impact on the response of pile-supported structures.

TL;DR: In this paper, the pseudodynamic approach, which considers the effect of primary and shear wave propagation in the backfill soil and wall, is adopted for calculation of the seismic earth pressure considering wall inertia.
Abstract: This technical note pertains to the study of a waterfront retaining wall, retaining a partially submerged backfill, subjected to seismic forces. The pseudodynamic approach, which considers the effect of primary and shear wave propagation in the backfill soil and wall, is adopted for calculation of the seismic earth pressure considering wall inertia. The point of application of the seismic active earth pressure is also affected by seismicity. Hydrodynamic forces are considered in the analysis. It is observed that when the horizontal seismic acceleration coefficient is increased from 0 to 0.3, there is a 65% decrease in the factor of safety of the retaining wall in sliding mode. To investigate the effects of different parameters on design, a parametric study is done. It is observed that with increase in the value of ϕ from 25 to 35° , there is an increase in the factor of safety in the sliding mode by 50%. Comparison with a previous study suggests that the present pseudodynamic approach gives less conservat...

TL;DR: In this paper, the static and seismic passive earth pressure coefficients for the general case of an inclined wall and a sloping cohesionless backfill were computed by using finite-element lower-bound limit analysis based on second-order cone programming (SOCP).
Abstract: Static and seismic passive earth pressure coefficients for the general case of an inclined wall and a sloping cohesionless backfill were computed by using finite-element lower-bound limit analysis based on second-order cone programming (SOCP). The comparison with the best existing upper-bound solution and the widely accepted solution obtained by the method of stress characteristics has shown that the present lower-bound solutions can provide a safe estimate of the passive earth pressures. Therefore, combining present results and upper-bound solutions can bracket the true value of passive earth pressures. In addition, design tables are presented that allow geotechnical engineers to easily use the present results in practice.
