CAPWAP - Static bearing capacity from PDA/DLT
The CAPWAP (Case Pile Wave Analysis Program) computer software allows full and accurate analysis of PDA field data. The force and velocity signals recorded in the field will be processed and a representative blow if selected for further analysis using the CAPWAP suite of computer software. CAPWAP analysis involves applying the measured pile top force and velocity-time as a boundary condition to a wave equation model of the pile. The pile-soil model will be continuously adjusted until a close agreement is obtained between the measured and computed pile top data. A typical presentation of CAPWAP results will be as follows:
· Total static and dynamic computed soil capacity - skin friction & end bearing component.
· Computed load-settlement curve response to the pile - simulation of static load test
· Skin friction distribution along the pile length.
A match curve of computed pile top force to the measured pile top force versus time records.

CAPWAP (Case Pile Wave Analysis Program) is actually a part of dynamic load test. With Pile Driving Analyser (PDA) we measure pile top force and velocity during impact pile driving, restricting or during dynamic load testing of bored piles and driven piles. Results may include bearing capacity predictions, pile stress checks, pile integrity verification and/or hammer performance
CAPWAP verifies the results of PDA calculation through rigorous numerical analysis. CAPWAP also calculates skin friction and end bearing resistance components and determines the dynamic behaviour of soil. The analysis service is a part of PDI's vibration PIT test report.

GRLWEAP - pile response to pile driving equipment
GRLWEAP software runs on the standard PC computers.
GRLWEAP is a one-dimensional "wave equation analysis" program for simulating the pile response to pile driving equipment.
GRLWEAP predicts driving stresses, hammer performance and the relation between pile bearing capacity and net set per blow (inverse of blow count per unit depth). This allows the user to investigate which hammer is likely to be sufficient and economic for a certain pile and soil condition prior to mobilising the hammer to the job. This advance computer simulation is easily performed in minutes, and helps avoid costly errors in judgement.

This simulation has a very user friendly interface beginning with files of pre-programmed hammers, which are called by a single ID number, extensive user help, and numerous automatic features (such as building the pile model). Extended options include driveability analysis, different stroke options for diesel hammers, soil sensitivity analysis, and models for parallel or composite piles.
In a variety of enhancements and options the program is able to predict:
· Capacity or stress vs. blow count/set.
· Residual stresses in pile and soil during driving
· Pile model with soil resistance parameters.

PLAXIS - geotechnical problems analysis

PLAXIS is a special purpose geotechnical finite elements program for Windows 95/NT. The comprehensive user interface makes the program easy to operate. After the graphical input (CAD) of the project geometry the Full Automatic mesh generator proposes a finite element mesh to the user in seconds. Robust automatic solution procedures ensure a smooth calculation process. Besides accurate modelling of soil behaviour, PLAXIS allows for realistic modelling of structures and the interaction of structures with soil.
