Research project - Tunnelling-induced pile foundation behaviour

Supervisor: Prof John Carter
Associate Supervisor: Prof John Small

The aim of this project is to discover the behaviour of pile foundation due to tunnelling.

One of the main concerns that arise from tunnelling in an urban setting is the effect of the induced ground movements on surrounding structural foundations. The foundation types considered in this study are pile foundations, which are commonly used to support high rise buildings in many major cities.

The first part of the study is to explore linear elastic behaviour of a single pile adjacent to a tunnelling excavation. A new numerical method analysis for elastic behaviour of a single pile due to tunnelling was proposed in this study. Results from parametric study conducted in this study were used to derive a new design charts for practising engineer.

The second part of this study is to explore non-linear elastic behaviour of a single pile. Non-linear analysis of the problem will be verified with results obtained from ‘1g’ test
