| Citation | Distinguished for his wide-ranging contributions to the principles and the application of soil mechanics. First at Cambridge, then as Head of the Geotechnics Division of the Building Research Establishment, and subsequently as leader of the soil mechanics group at Imperial College, his research work includes the development of critical state theory, field measurements of the deformation of geological strata, precision methods of measuring small strains in laboratory tests,and a synthesis of the mechanical properties of sedimentary deposits. His knowledge and expertise is recognised internationally,and he has been involved in many important engineering projects at home and abroad during the past twenty-five years. |
