Gravity and Cantilever Wall Analysis Program.
GWALL analyses a wide range of retaining wall problems including gravity walls and cantilever walls with a base.
Methods of Analysis
GWALL carries out two types of analysis within the one program:
A wide variety of wall geometries can be analysed including variable heel and toe width, battered front and back faces and a shear key at any position.
Up to 20 soil strata may be defined. For each stratum the following parameters may be specified:
The program will, if desired, calculate earth pressure coefficients from values of soil friction, wall friction, batter angle and backfill angle given by the user.
Hydrostatic or non-hydrostatic water pressure profiles may be defined on both sides of the wall.
Applied Loads and Surcharges
Surcharges may be specified to act on or below the ground surface on the active side.
Vertical, horizontal and moment loads may be applied to the top of the wall. Horizontal and vertical components of anchor load may be applied to the face of the wall.
Data may be entered in any consistent set of units e.g. (kN,m), (lb,feet). All print-out from the program is automatically annotated in the appropriate units.
Printed output from the program consists of the input data followed by details of the forces, factors of safety, wall pressures, bending moments and shear forces.
