GeoStudio 2007 provides comprehensive tools for performing analysis of excavations and open pit mines.
The Problem
Excavations cover a broad range of geotechnical engineering from building construction to open pit mining and can
be the basis for a wide range of analyses, depending on the questions being asked. Common to all issues in this
category is the release of locked in stresses when the soil or rock is unloaded. In addition, the presence of water
in the ground or free water on surface can greatly change the excavation behavior from a seepage and stability
perspective.
The Solution
GeoStudio 2007’s integrated suite of analysis tools provides a wide range of approaches for dealing with excavations.
Insitu stresses and pore-water pressure conditions can be established such that upon removal of the ground rebound
displacements can be computed. Steady state or transient pore-water flow systems can be simulated and incorporated
into dewatering and stability evaluations. Detailed stress paths can be monitored during these transient changes in
pore-water pressure. In an advanced analysis, sudden collapse of unstable ground can lead to slope failures in pit.
This can be accounted for. As always, a dynamic earthquake analysis can be carried out to assess the potential for
generation of excess pore-water pressures in the ground or plastic deformation due to stress-redistribution.
