PARAMETERISED MESH GENERATION FOR FINITE ELEMENT ANALYSIS OF TUNNELLING (2008)
This paper introduces a parameterised scheme for automated 3D mesh generation of highly complex tunnelling layouts using a freeware mesh generator. Comparisons are made with meshers found in commercial FE software
Reference: Computers and Geotechnics, 2008
THE STRENGTH OF RAMMED EARTH MATERIALS (2007)
This paper presents initial laboratory test results which point to the main source of strength in (unstabilised) rammed earth being due to suction, showing that it can be regarded as an unsaturated soil.

ANALYSIS OF HISTORIC RAMMED EARTH CONSTRUCTION (2006)
A novel approach to the modelling of rammed earth using finite elements is presented. Each rammed earth lift is modelled as two layers, one representing the actual rammed earth and one representing the interface between each rammed earth lift.

ON PRECONDITIONING STRATEGIES FOR GEOTECHNICS (2005)
This paper reviews the background to iterative methods for elastic and elasto-plastic material models. In some cases, existing numerical methods can be taken from research in the mathematics community.

INTERACTION BETWEEN MULTIPLE TUNNELS IN SOFT GROUND (2004)
This paper describes numerical analyses of multiple tunnelling undertaken using the commercial finite element software Plaxis. The aim of the study is to improve prediction of minimum interaction distance between multiple driven tunnels at shallow depths in ...

STRESSES AROUND SQUARE TUNNELS USING A MESHLESS SCALED BOUNDARY METHOD (2004)
The new method is used to model the stresses around a square tunnel in a linear elastic soil with insitu prestress, and is shown to be both more economical (in terms of degrees of freedom) and more accurate than a conventional displacement FE approach

MODELLING MASONRY ARCH BRIDGES USING COMMERCIAL FINITE ELEMENT SOFTWARE (2003)
Numerical models of masonry arch bridges are required for accurate determination of ultimate failure loads. Finite element analysis (FEA) has been surprisingly under-used in this area perhaps because the main features of masonry behaviour, namely strongly ...

THREE DIMENSIONAL MODELLING OF THE INTERACTION BETWEEN BUILDINGS AND TUNNELING OPERATIONS (2001)
The focus has been on the development of a predictive tool for assessing the probable damage to buildings

A TYING SCHEME FOR IMPOSING DISPLACEMENT CONSTRAINTS IN FINITE ELEMENT ANALYSIS (2000)
This paper describes the formulation of elements to connect finite element meshes of differing dimensionality. The formulation employs minimization using Lagrange multipliers. While this technique is already described in many texts, this paper demonstrates ...

2 DIMENSIONAL ANALYSIS OF SETTLEMENT DAMAGE TO MASONRY BUILDINGS CAUSED BY TUNNELLING (2000)
This paper describes a two- dimensional fnite element analysis in which the tunnel, the soil and a building are all treated in a single analysis.
