Description GWALL carries out two types of gravity and cantilever wall analysis: Limit equilibrium analysis for calculating factors of safety against sliding and overturning; Calculation of bending moments and shear forces in the stem and base (including the effect of earth pressures due to compaction). 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: Density; Friction angle and cohesion; Earth pressure due to compaction; Earth pressure coefficients. 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. 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. Data and results are displayed in graphical form either on the screen or in hard copy form on a dot-matrix or laser-jet printer. Graphical display of the data shows the shape of the wall, the soil profile, ground water levels, applied loads and anchor position (if present). Results are displayed in the form of bending moment, shear force and wall pressure diagrams.
