Book Description

Numerical Methods in Geotechnical Engineering IX contains 204 technical and scientific papers presented at the 9th European Conference on Numerical Methods in Geotechnical Engineering (NUMGE2018, Porto, Portugal, 25—27 June 2018). The papers cover a wide range of topics in the field of computational geotechnics, providing an overview of recent developments on scientific achievements, innovations and engineering applications related to or employing numerical methods. They deal with subjects from emerging research to engineering practice, and are grouped under the following themes:

  • Constitutive modelling and numerical implementation
  • Finite element, discrete element and other numerical methods. Coupling of diverse methods
  • Reliability and probability analysis
  • Large deformation – large strain analysis
  • Artificial intelligence and neural networks
  • Ground flow, thermal and coupled analysis
  • Earthquake engineering, soil dynamics and soil-structure interactions
  • Rock mechanics
  • Application of numerical methods in the context of the Eurocodes
  • Shallow and deep foundations
  • Slopes and cuts
  • Supported excavations and retaining walls
  • Embankments and dams
  • Tunnels and caverns (and pipelines)
  • Ground improvement and reinforcement
  • Offshore geotechnical engineering
  • Propagation of vibrations

Following the objectives of previous eight thematic conferences, (1986 Stuttgart, Germany; 1990 Santander, Spain; 1994 Manchester, United Kingdom; 1998 Udine, Italy; 2002 Paris, France; 2006 Graz, Austria; 2010 Trondheim, Norway; 2014 Delft, The Netherlands), Numerical Methods in Geotechnical Engineering IX updates the state-of-the-art regarding the application of numerical methods in geotechnics, both in a scientific perspective and in what concerns its application for solving practical boundary value problems. The book will be much of interest to engineers, academics and professionals involved or interested in Geotechnical Engineering.
