Short piles response to lateral loading in dense sand at Blessington
Short piles response to lateral loading in dense sand at Blessington
This paper presents some initial results of an experimental campaign aimed at extending the existing database of pile lateral field tests. Monopiles with low slenderness ratios (L/D, ratio of pile embedment to pile diameter) close to 3 are deemed to be representative of current and future monopile foundation designs for the offshore wind industry. The monopile field testing consisted of both monotonic and cyclic tests with slenderness ranging from 2.2 to 4.4. A total of 6 piles with an outer diameter of 457 mm were driven and tested in dense sand at the Blessington test site, located south to Dublin in Ireland. This paper provides some insight into the results of the monotonic and cyclic tests presented in terms of load-displacement responses at ground level as well as accumulated pile displacement and change in unloading-reloading stiffness as a function of the number of cycles.
