The Analytical Challenge

The design of reinforced walls and slopes is a common geotechnical activity. Reinforcement may be through anchors, soil nails, or geotextiles. The numerical modeling challenge is to correctly account for the stresses between the reinforcement member and the soil such that the stability of the design may be evaluated. Some designs may also require computation of the expected deformations. The analytical challenge is related to proper computation of stress state and potential related deformations.

The SVOFFICE™ Solution

SVOFFICE™ provides rigorous implementation of the analysis of soil nails, multiple types of anchors, micropiles, geotextiles as well as user defined members in our SVSLOPE® limit equilibrium slope stability analysis software. The solutions may be analyzed in 2D or in 3D. 3D analysis is ideal because anchors are fundamentally point loads and should theoretically be analyzed in 3D software. It is also possible to analyze anchors in a finite element stress-deformation analysis using the SVSOLID™ software. Anchors can be analyzed in 2D or 3D using SVSOLID™ and a prediction of deformation as a result of a particular anchor design can be computed.

 

  • The Challenge
    Construction of sheet pile walls requires calculation of the active and passive pressures along the wall and at the base. Inadequate designs can lead to unacceptable deformations of the wall.

    The Solution
    SVSLOPE® is designed to calculate the factor of safety of such sheet pile wall scenarios. SVSOLID™ can also be utilized to calculate the deformations of a particular design.

  • The Challenge
    Geotextiles are increasingly used to stabilize retaining walls. The modeling of geotextiles in the design requires the representation of thin tensile members.

    The Solution
    Such geotextiles can be represented in 2D and 3D models using SVSLOPE®. The water flow around such geotextiles can be modeled in SVFLUX™.

  • The Challenge
    Gravity walls reinforce a slope with their own weight through passive resistance to movement. The numerical challenge is to design for a reasonable factor of safety as well as minimizing deformations..

    The Solution
    SVSLOPE® utilizes the limit equilibrium method in order to calculate the factor of safety for such design. SVSOLID™ can be utilized to calculate expected deformations after placement of gravity wall.

  • The Challenge
    Mechanically stabilized earth involves compaction, loose sand vibrostabilization, and densification to improve the strength of earth.

    The Solution
    SVSLOPE® and SVSOLID™ have many constitutive models in order to model the effects of MSE structures. Modeling the effects in terms of factor of safety or deformations in 2D or 3D can be performed.
