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.
GeoStudio has many different options for dealing with structural reinforcements. In a more rigorous analysis,
the structural component properties can be included in a stress-deformation analysis such that the forces and
moments in the structure can be computed along with the interaction between the structure and ground. In a less
rigorous approach, a stability analysis can 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 automatically at different stages of
construction to simulate actual field conditions. There is a friction based interface model in SIGMA/W to allow for
soil-structure interaction with or without slippage. Whether you are concerned about wall loading, deformations, or
stability, GeoStudio has a method of investigating your concerns.
