D-Sheet Piling – Feasibility
During the design of a sheet pile wall, the stability of the construction is checked according to guidelines like the Eurocode. In practice, this does not guarantee that the project is feasible. This may depend on many other local factors, among which the equipment used during construction. For this purpose, the use of the Feasibility module helps the user to evaluate the project’s feasibility by comparison with experiences.
There are three sources are available in the Feasibility module:
The Dutch Society for Foundation Engineering Contractors ( NVAF) has written guidelines to prevent sheet pile driving failure. The Feasibility module supports some NVAF graphs on pile driving failure, using vibrators. These graphs are based on the relation between the sheet pile length and the resisting moment. Depending on the equipment used, several graphs exist that giving the user an indication of the feasibility.
GeoBrain foundation technics experiences
In 2002, GeoDelft started a project called GeoBrain which aim was to develop a prediction model for the feasibility of foundation works. Hundreds of project experiences concerning the driving of sheet pile walls and piles were therefore received for study. The Feasibility module provides access to these experiences. Based on the relation between the sheet pile length and the resisting moment the user is confronted with stored experiences. These can help the users to predict the feasibility of their projects.
GeoBrain Foundation technics predictions
The GeoBrain Foundation technics prediction model introduces expert knowledge based on input parameters used in D-Sheet Piling . The prediction model will indicate the feasibility of the project and provide suggestions for practical improvements.
Feasability comes as a standard module in the D-Sheet Piling Basic package, together with Earth pressure coefficients. It can be extended with other modules to fit more advanced applications. For more information, see Service packages.
