PileAXL - Design and analysis for single piles under axial loading 

PileAXL is a program that analyzes the behaviour of single piles under axial loading applied at the pile head for both onshore and offshore engineering problems. 

Main Benefits


Fast and efficient creation of axial capacity and settlement analysis problem for single piles


The user-friendly interface enables the user to efficiently create the analysis input file for single piles under axial loading with a logical workflow.



Comprehensive analysis models available for pile axial capacity 


PileAXL provides a wide range of axial capacity models for determining ultimate shaft resistance and end bearing resistance of both driven and bored piles for clay, sand and rock.  Imported CPT profile is also supported for calculating the axial capacity of driven piles and drilled shaft or CFA piles based on the various CPT-based method such as ICP, NGI, UWA, Furgo and LCPC

Easy parameter input for various soil and rock materials


Various soil parameters for different axial capacity calculation methods can be easily input by the users. The program also provides built-in tool to help users to select empirical parameters.

Calculating Load Settlement Curves with T-Z and Q-Z Curve Models


PileAXL provides a wide range of T-Z curve and Q-Z curve models for the pile settlement analysis using the load transfer method. The user-defined models are also supported for T-Z and Q-Z curves.

A simple way to access and view all the analysis results on one window dialogue


All analysis results such as shaft resistance, end bearing resistance and pile axial capacity including design strength values based on design standards are presented on one window dialogue. It is easy for the users to switch among different result plots and copy or print if required. 


Supporting various pile axial capacity design codes

PileAXL currently supports the following design codes:

(1) Working load design approach

(2) AASHTO (American Association of State Highway and Transportation Officials)

(3) Eurocode 7 - UK (DA1)

(4) Eurocode 7 - (Others)

(5) Australian Standard AS 2159 - 2009

(6) Eurocode 7 - Singapore National Annex

(7) Eurocode 7 - Malaysia National Annex



Nonlinear T-Z and Q-Z curve generation along the pile length and graphical presentation 


Generation and graphical presentation of nonlinear T-Z and Q-Z curves along the pile length for various soil types such as cohesive soils, cohesionless soils and rocks. The detailed calculation information at the selected location can be viewed by the users.

Graphical presentation of axial load settlement curves for different pile lengths

Load settlement curves at the pile head are presented for difference pile lengthsIt is easier to switch on and off the results for the selected pile lengths. This is a very useful feature as the users can compare the effects of different pile lengths.

Lateral capacity analysis for short piles 

A simple tool - SPileLAT is available in PileAXL for lateral capacity analysis of short piles. It can be used to determine the capacity of the short piles under later force and bending moment applied at the pile head based on Broms method for cohesionless and cohesive soils and Hong Kong Geoguide method for rocks. Three different design approaches are available in SPileLAT: (1) Allowable working load design; (2) Limit state design - AASHTO and (3) Limit state design - Australian Piling Standard 2159-2009. 



CPT manager tool  

Cone penetration test (CPT/CPTu) data can be imported into the program for pile axial capacity and settlement analysis with the built-in CPT manager tool in the program. Various axial capacity methods based on CPT data such as ICP, NGI, Furgo, UWA and LCPC methods will use the imported CPT data to calculate the shaft resistance and end bearing resistance.
