DESCRIPTION: Niels Krebs Ovesen laid the foundations\, as it were\, for sc
 aling effects in centrifuge modelling by investigating in a characteristic
  and meticulous fashion\, the validity of physical modelling using small s
 cale models under enhanced gravity. Initially\, he carried out bearing cap
 acity tests on circular footings on sands\, focussing on the influence of 
 gravity level and scale\, which he later reported with great clarity in G
 éotechnique. This paper and his subsequent one to the ECSMFE in Brighton 
 in 1979 are classics.\n \n\nFurther research into uplift resistance to anc
 hors and reinforced embankments on soft clays followed in the new Danish g
 eotechnical centrifuge. As Niels moved over towards turning his concept of
  a pan-European codification based on partial factors\, into reality\, he 
 still remembered the importance of having real data from a 'real' physical
  event to be able to assist in design. His legacy to physical modelling is
  that this has now been written into the Eurocode (and the Swisscode) as a
  means by which a design may be evaluated and proven.  \n\n
