There is a high risk that the sheet piling will not reach depth.
Recommended mitigation measures to reduce risk
Pre-drilling
Pull-down
Water jetting
Fluidization
Reduce lock friction
Post-driving
Figure 8.13 Result of a prediction using GeoBrain Foundations (installation sheet piling)
An example of the use is shown in Fig 8.13, for sheetpile installation in
GeoBrain Foundations, created by Hemmen and Bles 39 . The input is a soil profile
and CPT, and the choice of equipment and material. The system will then provide a
prediction of the risk of malfunction, based on the probabilities in the experience
database, shown by a bolt in a strip running from high to low risk. The system will
also provide mitigation measures to improve the approach. Here, six potential
measures are listed: predrilling, pull-down, water jetting, fluidization, reducing
lock friction, or post-driving, each with their risk effect shown in a horizontal bar.
This information is important for the user to estimate risk and cost, and make a
final decision how to execute the work.
The use of Geobrain is restricted to members. GeoBrain Foundations proves that
sharing experience is beneficial: unnecessary risks are avoided in a systematic
manner.
39 GeoBrain Foundations was supported by the Dutch Association for Contractors in
Foundation Engineering (NVAF), ProRail, CROW, Allianz, Cunningham and Lindsey,
AON and Clark Risk Management, the Ministry of Transport, Public Works and Water
Management, Municipality of Rotterdam, BAM Civil Techniques, CFE, Ballast Nedam
Foundation Techniques, Terracon Foundation Techniques, Voorbij, MUC and Deltares
(leader).
