In-situ full scale loading tests were conducted in the Northern Gulf of Bothnia in order to measure the ridge keel mechanical properties. Altogether 33 loading tests in full scale were conducted during five winters (1998-2003). 12 of them were punch shear tests, in which a circular plate of the cons...
