Reinforced Walls and Slopes

GeoStudio provides comprehensive tools for analyzing reinforced walls and slopes.

The analytical challenge


Many classes of geotechnical engineering projects require additional mechanical support to ensure stability during and after construction. This mechanical support may range from geosynthetics to tie-back anchors or retaining walls. Excavations are often preceded by installation of sheet pile walls and then these are anchored or braced as construction proceeds. Stresses in the structural components need to be estimated so that they can be designed to accommodate the anticipated loading. Man-made or natural slopes are often reinforced to increase stability and minimize risk.

The GeoStudio solution


GeoStudio has many options for dealing with structural reinforcements. In a more rigorous analysis, the structural component properties can be included in a stress-deformation analysis so the forces and moments in the structure can be computed along with the interaction between the structure and ground. A stability analysis can also be carried out with all or part of an assumed structural load component applied to the sliding mass. Structural components can be applied and removed to simulate actual field conditions. Whether its wall loading, deformations, or stability, GeoStudio has a method to address your concerns.

Berlin Tie-Back Wall

The objectives of this example are to demonstrate that SIGMA/W has sufficient features and capabilities to simulate the construction sequence, to illustrate the procedures and techniques that are required to obtain close agreement between the predicted and measured wall deflections, and to highlight the key modeling issues in a situation like a tie-back wall with pre-stressed anchors.

Braced Deep Excavation in Soft Ground

Halim and Wong's paper in Underground Singapore 2005 presents six case histories where deflections of the shoring walls were measured during construction. The case histories show that GeoStudio has the capabilities to model the behavior of deep shored excavations in soft ground.

Reinforcement with Soil Nails

The purpose of this illustrative example is to show how soil nails can be used to improve the stability of a slope. Features of this simulation include: analysis method: Morgenstern-Price, homogenous soil with Mohr Coulomb soil model, a dry slope with no pore-water pressure, four sloping soil nails, entry and exit slip surface option.

Stability of an MSE Wall

Mechanically stabilized earth (MSE) walls are structures for retaining the earth under bridges, highways, water front ports, and other forms of infrastructure. Designing an MSE wall requires consideration of the geometric configuration and reinforcement requirement to ensure both internal and external stability.
