TL;DR: In this paper, the effect of seepage flow on the lateral earth pressures acting on deep sheeted excavations in cohesionless soil was investigated using the explicit finite difference method implemented in Fast Lagrangian Analysis of Continua (FLAC) code.
Abstract: This paper deals with the effect of seepage flow on the lateral earth pressures acting on deep sheeted excavations in cohesionless soil. The computation of the passive and active earth pressures in the presence of hydraulic gradients is performed using the explicit finite difference method implemented in Fast Lagrangian Analysis of Continua (FLAC) code. The available effective passive earth pressure coefficients in the presence of upward seepage forces are given for both associative and non-associative material. The present solutions show that the soil dilation angle influences the effective passive earth pressures for large internal friction angle values of the soil. They also show that the effective passive pressures diminish with the hydraulic head loss. Good agreement is observed between the present results and those using an upper-bound approach in limit analysis for an associative material. For the active case, the effect of downward seepage forces on the active earth pressures is investigated. The ...

TL;DR: In this article, a method for soil stability analyses applying principles of soil mechanics to the theory of plasticity (limit analysis approach) is presented, which is applicable for: (1) design and failure conditions; (2) short and long-term analyses; (3) soil with pore water that is either stagnant or in seepage motion; (4) layered medium; and (5)arbitrary number of degrees-of-freedom of structure or support.
Abstract: A method for soil stability analyses applying principles of soil mechanics to the theory of plasticity (limit analysis approach) is presented. The rigorous theoretical background and the simplicity of both the method and the calculation procedure are encouraging application of the method in engineering practice. Attention is drawn to the implication of the boundary conditions of deformations (degrees-of-freedom of the investigated structure or support) for the analysis. Different numbers of degrees-of-freedom of a system generally yield different results for safety factor, bearing capacity, etc. The method can be used for bearing capacity, earth pressure, and slope stability analyses. It is applicable for: (1)Design and failure conditions; (2)short and long-term analyses; (3)soil with pore water that is either stagnant or in seepage motion; (4)layered medium; and (5)arbitrary number of degrees-of-freedom of structure or support.

TL;DR: In this paper, the performance of a tiedback excavation with a soil mixed wall in Boston where underlying marine clay was stabilized by deep soil mixing (DSM) and jet grouting was evaluated.
Abstract: This paper describes the performance of a tiedback excavation with a soil mixed wall in Boston where underlying marine clay was stabilized by deep soil mixing (DSM) and jet grouting. Lateral and vertical soil displacements, soil strains, and tieback loads are evaluated. The interaction between the retained soil and a reinforced concrete box culvert, supported on drilled shafts, is described. Piezometer measurements behind the wall are summarized. They show pore-water pressures in marine clay substantially less than the hydrostatic pressures assumed in design.

TL;DR: In this paper, the vertical component of soil pressure was found to decrease more rapidly with depth than predicted by the equation usually used in soil mechanics, and the results were discussed in terms of detailed measurements of soil penetrometer resistance, bulk density and water retention characteristics.

TL;DR: In this paper, the authors examined the provisions of the American Association of State Highway and Transportation Officials' (AASHTO) "Standard Specifications for Highway Bridges" relative to design of reinforced concrete box culverts.
Abstract: Study critically examines the provisions of the American Association of State Highway and Transportation Officials' (AASHTO) "Standard Specifications for Highway Bridges," relative to design of reinforced concrete box culverts. This paper deals specifically with two topics: soil pressure analysis was performed by finite element modeling taking into account soil-structure interaction. The analysis confirms previous field observations that the AASHTO provisions considerably underestimate soil loading. Formulas are proposed for prediction of more realistic soil pressures. Influence of the proposed soil pressures on culvert size and reinforcement is demonstrated by numerical examples. Both the working stress design and the strength design methods are employed. It is shown that, even with the increase in soil pressures as suggestsed, use of the more rational strength design method could result in material savings.
