Abstract
A complex three-dimensional finite element model has been
developed to study the effects of tunnel construction on
adjacent structures. The model uses an in-house finite
element code in which complex simulations and non-linear
material models have been developed. This paper describes
the transfer of this code to a large parallel computer, and the
improvements in performance that resulted from the move.
The examination of the code, which was necessary for the
transfer, also led to improvements in the serial version.
1 Introduction
Numerical modelling of geotechnical engineering problems
has been carried out in the Civil Engineering Research Group
at Oxford since 1980. Finite element analysis is performed
using the in-house finite element program, OXFEM, written
in Fortran 90 and running on Unix workstations. A particular
area of interest of the group, since 1992, has been the
modelling of soft ground tunnelling and the interaction
between the effects of tunnel construction and surface
