Introduction
I work as a doctoral researcher in geotechnical engineering at the University of Galway as part of the Digital Construction Underground research group (https://dcu-group.co.uk/). My research focuses on real-time field monitoring of microtunnelling drives, through which we aim to identify the complex soil-structure interaction effects that govern their design. The research is carried out in collaboration with the University of Cambridge and the industrial partner, Ward and Burke Construction.

Description
- Studied the dynamic Soil-Structure Interaction (SSI) effect of new underground construction on existing nearby buildings, using FEM software PLAXIS for modeling. Hardening Soil with Small Strain Stiffness constitutive model was calibrated to capture the non-linear SSI effect of soil. Validation of the numerical model was done using geotechnical centrifuge testing data of Kenneth Gillis et al. (2015).

Position
- Geotechnical Research Intern
Description
- Worked as an intern with a geotechnical engineering research team in which the behavior of clay at varying sand and moisture contents was studied, under Unconsolidated Undrained triaxial loading. I presented our findings in the 4th Pak-Turk International Conference.

Microtunnelling or pipe jacking (PJ) is the preferred method of utility pipeline construction in congested urban environments due to its minimally disruptive nature. In this study, a 1490 mm outer diameter reinforced concrete (RC) jacking pipe was instrumented for incorporation within a 297 m long curved PJ drive as part of the Athlone Main Drainag...
The popularity of trenchless techniques as a means of utility pipeline installation in urban environments, specifically microtunnelling/pipe-jacking, has increased in recent years due to its minimally-disruptive nature and reduced carbon footprint in comparison to conventional open-cut excavation methods. The response of pipes during the jacking pr...
Total jacking force capacity is a key design consideration when constructing pipelines using the pipe-jacking
(microtunnelling) technique. The total jacking force must match the force at the tunnel boring machine face plus the frictional
force between the pipeline and the surrounding ground. In this paper, 15 historical pipe-jacking drives, constru...
Questions
Question (1)
I am working on development of an instrumented pipe for micro-tunneling, there are sensors in the pipe which will measure hoop strains. Is it possible to convert the observed hoop strain to flexural or bending strains?
