GeoStudio 2D Advanced
2D geotechnical engineering analysis software
GeoStudio 2D
GeoStudio 2D offers the foundational capability to perform Limit Equilibrium slope stability analysis using SLOPE/W for soil and rock for problems that do not require the consideration of groundwater flow, finite element stresses or pore-water pressures, or dynamic stresses.
GeoStudio 2D Advanced
GeoStudio 2D Advanced includes SLOPE/W and SEEP/W and offers all the essential capabilities of the GeoStudio 2D tier, while introducing the ability to simulate steady-state and transient groundwater flow in both saturated and unsaturated soil and rock using SEEP/W.
GeoStudio 2D Advanced can be used to analyze geotechnical engineering challenges across the value chain, including rapid drawdown analysis, complex seepage analyses, dewatering problems, and much more.
GeoStudio 2D Ultimate
GeoStudio 2D Ultimate includes SLOPE/W, SEEP/W, SIGMA/W and QUAKE/W and expands the capability of the GeoStudio 2D Advanced tier with functionality to deal with the most challenging geotechnical projects. It includes the ability to analyze static and dynamic stress and deformation within soil or rock using SIGMA/W and QUAKE/W, including coupled consolidation, finite element stress stability, and the ability to use finite element results in SLOPE/W.
GeoStudio 2D Ultimate can be used to analyze geotechnical engineering challenges across the value chain, including stress and pore-water pressure response in complex loading and unloading construction sequences, earthen and tailings dam construction and operation, and much more.
“We used GeoStudio to replicate measured pore water pressures and track factor-of-safety vs. time – even turning our modeled wick drains “on” and “off” to produce a failure at the same time and under the same conditions as actually occurred; that calibration analysis allowed us to model a reconstruction scenario with some 30,000 cubic yards of foam fill and predict/prescribe threshold pore water pressure and deformation values for field validation.”
