Dredging And Dredged Material Beneficial Use In Ireland, Colm Sheehan, Joseph R. Harrington, Jerry Murphy
Dredging And Dredged Material Beneficial Use In Ireland, Colm Sheehan, Joseph R. Harrington, Jerry Murphy
Publications
This article provides an overview of the dredging industry in Ireland which may be small by international standards but is of critical importance to the nation’s Ports and Harbours. Open sea disposal of dredged material is most common, but a range of beneficial uses for the coarser fraction of dredged material has been practiced. Details on different aspects of dredging in Ireland are presented including a review of current beneficial uses. A specific site at Fenit Harbour in Tralee Bay is examined to assess the potential for a specific beneficial use of dredged material using geotubes in breakwater and revetment …

Shaft Capacity Of Continuous Flight Auger Piles In Sand, Kenneth Gavin, David Cadogan, Patrick Casey

This paper presents the results of a series of field experiments performed to study the development of shaft resistance on continuous flight auger piles installed in sand. The test piles were instrumented in order to separate the shaft and base resistance, and to allow the determination of the distribution of shaft resistance along the pile shaft. The tests highlighted the importance of accurate calculation of the shaft resistance for nondisplacement piles. At a typical maximum allowable pile head settlement of 25mm, more than 71% of the pile resistance was provided by shaft friction. Conventional methods of estimating shaft resistance were …
