GGU-AXPILE: Preface

The GGU-AXPILE program allows calculation of bored piles to DIN 4014 and of driven piles according to Franke (Geotechnical Engineering Handbook (GEH) 2003; Part 3) and the graphical representation of the results. Tension piles can also be calculated. Both the global safety factors to DIN 1054 (old) and the partial safety factors to DIN 1054:2005 or EC 7 may be taken into consideration.

The Recommendations of the Working Group on "Piles" (EA-Pfähle - EAP) were published in April 2007. These recommendations allow the design of many cored and driven piles via design tables. In these terms, the EAP represents current best practice. Annexes to the DIN 1054 will be replaced in the future by references to the EAP. In the GGU-AXPILE program the EAP analyses methods were implemented for pile design.

Depending on the soil properties, the pile length or the pile diameter/pile side width are varied, and the allowable pile load calculated. The allowable pile load is represented as a function of the pile diameter or the pile length, determined by the type of variation selected (pile length or pile diameter). Alternatively, the detailed analysis results can also be displayed for a single pile.

The program includes convenient data input. The system is permanently displayed on the screen. Every change to the data is displayed on the screen, so that optimum control of the input data is guaranteed.

There are "?" and "Info"’ buttons in the dialog boxes for many technical and program-specific questions. Click on the "?" buttons or "Info" buttons to obtain the necessary information.

The graphic output supports the true type fonts provided by WINDOWS, so that an excellent layout is guaranteed. Colour output and numerous graphic formats (BMP, TIF, JPG etc.) are supported. PDF and DXF files can also be imported via the integrated Mini-CAD system (see "Mini-CAD" manual).

The program has been extensively tested. No errors have been found. Nevertheless, liability for completeness and correctness of the program and the manual, and for any damage resulting from incompleteness or incorrectness, cannot be accepted.
