Prof. Dr. Malcolm Bolton

Emeritus Professor, Cambridge University, UK

Malcolm Bolton graduated in Engineering from Cambridge University in 1967 and took an MSc by research in structural engineering from Manchester University followed later by a PhD in soil mechanics from Cambridge. His academic career in geotechnical engineering started in Manchester where he helped to develop the UK’s first geotechnical centrifuge, but in 1980 he returned to Cambridge where he is Professor of Soil Mechanics, and Director of the Schofield Centre for Geotechnical Process and Construction Modelling.
He is the author of a book and 220 publications covering the fundamental mechanics of granular materials and a wide variety of civil engineering applications from tunnels through foundations, and from earthquake effects to landslide hazard reduction. He served on the drafting panel of the UK Code of Practice on Earth Retaining Structures, and on the Slope Stability Technical Review Board of the Hong Kong Government. Professor Bolton acts as a consultant to oil companies and offshore engineering companies in relation to soil-pipeline interactions on the sea bed, He was chairman of ISSMGE TC105 “Geomechanics from Micro to Macro” for 10 years. Professor Bolton holds various prizes from the UK Institutions of Civil Engineers and Structural Engineers and is a Fellow of the UK Royal Academy of Engineering.

Research interests

Professor Bolton’s goal is to de-mystify soil mechanics and provide useful tools for prediction and decision-making by observing and comprehending mechanisms of behaviour, both of geo-materials and geo-systems. For example:

  1. Using Discrete Element Modelling (DEM) to clarify the behaviour of granular materials by relating the evolving deformability and strength of an assembly of grains to the elementary characteristics of a grain and of the assembly.

  2. Characterization of the non-linear stiffness and strength of soils in terms of easily measured parameters, by the statistical fitting of algebraic expressions to the data of published element tests.

  3. Using centrifuge model tests to clarify the behavioural mechanisms of geotechnical constructions – including shallow foundations, pipelines, piles, retaining walls, slopes, excavations and tunnels – during their construction, normal service, and exceptional loading.

  4. Developing Mobilizable Strength Design (MSD), by which simplified deformation mechanisms can be used to predict ground and structural distortions.

  5. Applying MSD to case studies of field construction and loading for a variety of applications, to confirm its applicability through back-analyses, and to derive dimensionless charts for future design and decision-making.

  6. Developing objective tools for the prediction of both the deformation and failure of geotechnical constructions, to advocate performance-based design methods which can replace existing methods based on cautious estimates of soil strength and arbitrary safety factors.

  7. Improving the understanding of piling systems for foundations or lateral support, focussing both on installation technology and performance in situ.

Chairman of the International Press-In Association, an organisation with over 700 members dedicated to improvements in the science and technology of pile installation and the behaviour of implant structures.
