About the Project
One major limitation of previous studies is that the structural geology aspect, primarily modelling the effect of strike and dip angle and the effect of interlocking arising from asymmetrical bed angles are not modelled. This results in overdesign of the pipe, as interlocking of soil grains naturally prevents large deformation of tectonic plates. A multidisciplinary approach needs to be undertaken in this research, where the non-linear plastic hardening-softening behaviour of the surrounding soil is modelled accurately. Although a number of research works have been undertaken on the pipeline stability issues, much of them have modelled the soil as elastic springs, which is not realistic.
To date, no plasticity-based soil models have been used to represent the soil behaviour in the fault zone, hence a rigorous soil-structure interaction model needs to be developed. Computer simulations will be carried out using world class CQU-HPC facilities within continuum and discrete finite element methods. Recognition of very large fault movements or high pipe strain requires exploring other modelling options such as the Coupled Eulerian Lagrangian (CEL) approach as well as particle-based finite element methods with suitable material subroutines developed in Fortran and Python. Extensive parametric studies are planned, not limited to pipe geometry, internal pressure and soil material properties. Preventive measures such as using a textured Pipe, ground anchoring using helical piles etc will be modelled and their effectiveness.
How to ApplyResearch Higher Degree candidates apply via iStart with an Expression of Interest which asks you to select your course and location, along with providing a brief description of your proposed research topic. Expression of Interest must be submitted by the prospective candidate.
Depending upon the outcome of your Expression of Interest, you may be invited to submit a full application for admission as a research higher degree candidate. The University reserves the right to refuse admission to any applicant.
Application DeadlinesOur Research Higher Degree courses don’t have any deadlines as students can commences these courses at anytime.
The project is suitable for civil engineers with interests in soil mechanics, numerical modelling and geotechnical engineering. Engineering geologists with some numerical modelling experience or experience in using finite element software are also encouraged to apply
