Numerical modelling in geotechnical engineering has become ever more critical
due to the higher level of variability and unpredictability of design parameters
extracted from ground investigations. As a result, checking the validity of numerical
models has become even more crucial.
The developments of various modelling software have created a requirement for
greater understanding of methods and underlying assumptions used, in particular
the need to check input parameters and constitutive models. Modelling issues
such as meshing routines and element types are an aspect that needs further
consideration. Additionally, calibration of models through more stringent
testing of elements and components within chosen software would help build
stronger confidence from modellers in the eventual outputs applied to future
CIRIA is planning to develop guidelines that will help alleviate some of the
issues along with additional training and development of less experienced
modellers which is integral to understanding the formation and behaviour of
complex numerical models. The benefits of adequate numerical modelling
- Reduced risk through an improved qualitative understanding of problems being
- A reduction in time and resources to correct any problems that do arise
further down the line of geotechnical designs.
- Consistency and uniformity within the industry.
CIRIA is seeking engagement with industry and funding support for the project.
