GEOTECHNICAL ANALYSIS

Modules are available for the solution of commonly encountered problems in the soil and rock mechanics fields. The

geotechnical analysis modules are categorized as follows:

All geotechnical analysis programs can be run in a deterministic or probabilistic mode:

SOIL MECHANICS MODULES

The following soil mechanics modules are available:

 

SLOPBG allows the analysis of a generalized soil slope using Bishop's modified method. The slope may be subjected to line and uniformly distributed loads, may be reinforced with metal strips or geofabric, may be clad and may be stabilized with anchors. The slope may consist of material of differing shear strength properties and faults and discontinuities can be defined.

Water pressures are accounted for using either a phreatic lines, pore pressure contours or a single pore pressure coefficient.

Horizontal and vertical seismic forces are considered. The program can search for the critical minimum factor of safety circle.

 

SLOPNC can be used for the analysis of a generalized soil slope using Sarma and Bhave's non-vertical slice method. The slope may be subjected to line and uniformly distributed loads, may be reinforced with metal strips or geofabric, may be clad and may be stabalized with anchors. The slope may consist of material of differing shear strength properties and faults and discontinuities can be defined. Water pressures are accounted for using either a phreatic lines, pore pressure contours or a single pore pressure coefficient. Horizontal and vertical seismic forces are considered. The program can search for the critical minimum factor of safety slip surface.

The ultimate bearing capacity of a shallow foundation can be evaluated with BCAP. The foundation may be rectangular or circular, the base and external ground slope may be angled and the forces imposed on the base may be from any direction.

Both drained and undrained conditions can be evaluated.

 

 

ROCK MECHANICS MODULES

The following soil mechanics modules are available:

WEDGE is used for the analysis of a tetrahedral wedge formed by the intersection of two planar discontinuities in a rock slope. Cable and bolt tension an external loading can be specified. The effects of water pressures on the discontinuities are also included.

 

 

ROCKPF is useful to calculate the factor of safety of a planar failure in rock for a range of input parameters. Tension cracks, seismic action and anchor forces can be entered.

Use ROCKJRM to evaluate the non-linear shear strength/normal stress envelopes for a range of input parameters. Output consists of instantaneous cohesion and friction values and actual shear strength for a given normal stress.

 

ROCKJR can be used to evaluate the shear strength failure of rough joints in rocks for a range of input parameters.

Supported theories include that of Ladanyi and Archambault and that of Barton.
