DFI Europe short course:

Pile Testing: State of the art

When: Thursday 10 and Friday 11 September 2009

Where: Radisson SAS Royal Hotel, Copenhagen, Denmark

DFI Europe will organise their third short course on the testing of pile foundations

on Thursday 10 and Friday 11 September 2009 in Copenhagen. This event will present the

‘state of the art’ in both pile load testing and integrity testing. Attendees are expected

to come from all European countries but more specifically from all Nordic countries

(Denmark, Finland, Norway and Sweden).

Pile Integrity Testing (Sonic Integrity Testing) (Peter Middendorp)

Pile foundations are widely applied in areas with the soft soil conditions, like the Netherlands. One ofthe popular pile types are cast-in-situ piles, which have to be integrity tested to get accepted. The application of pile integrity testing (sonic integrity testing) was developed in the Netherlands inthe 1960’s. With the number of integrity test performed nowadays, exceeding 400,000 per year, milli-ons of piles have been tested. Subsequently there is a substantial amount of practical experience withthis testing method and advantages and limitations have become more clear. The presentation will dealwith the basics of integrity testing and describe some of the techniques that have been adopted in theDutch pile testing practice, like detection of pile head defects with a spike type hammer pulse, and thesite average or pile group average for the qualitative interpretation of measured signals. The latestdevelopments in hardware and software will be presented. Special attention will be given to the limi-tations of pile integrity testing.

Rapid Load Testing of Piles - Statnamic Load Test (Adriaan van Seters)

In case of a rapid pile load test, the pile is loaded with a load of short duration. However, the durationis such that the pile is loaded in compression over its whole length. The complete pile penetrates intothe soil with a uniform velocity. Dynamic effects are of minor influence. The test is performed by pla-cement of a reaction mass on the pile head. By ignition of fuel the reaction mass is launched with anacceleration of 20 times gravity. Due to Newton's law an equal force is executed on the pile head.Using this method piles were loaded with 4 MN to 30 MN load using a mass of only 20 to 150 tonnes.The great advantage of the type of testing is thus that only 5% of the weight is required in comparisonwith a conventional static load test. The test results in a load-settlement hysteresis cycle, as the pileis loaded and thereafter unloaded. From this cycle, points of the static load settlement curve can bederived using for example the Unloading Point Method. An interpretation guideline is drafted in theDutch Committee on Rapid Pile Load Testing and an execution procedure will be implemented by asEuropean Testing Code. These guidelines will be discussed by examples in the presentation.

Biaxial Loadtest - Osterberg Cell (Melvin England)

The Fugro Loadtest presentation on Friday 11th September 2009, will be by Dr England who will coverthe subject of static load testing, from automation of top-down loading tests and the merits thereof, tointerpretation of results using methods such as Timeset/Cemset (displacement-time and load-settle-ment analyses). He will also present a summary of the latest experiences with bi-directional testingusing the Osterberg cell methodology for testing various piles types and barrettes.

The sessions will include time for discussion to allow participants to ask questions and discuss anyaspect of pile testing.
