Journal Article
Cuccurullo, A., Gallipoli, D., Bruno, A., Augarde, C., Hughes, P., & La Borderie, C. (2022). Earth stabilisation via carbonate precipitation by plant-derived urease for building applications. Geomechanics for Energy and the Environment, 30, Article 100230. https://doi.org/10.1016/j.gete.2020.100230

Raw (unfired) earth represents a sustainable and efficient alternative to traditional construction materials but its dissemination into building practice has been hindered by a relatively high vulnerability to water erosion. Enzyme induced carbonate... Read More about Earth stabilisation via carbonate precipitation by plant-derived urease for building applications.

A cone penetration test (CPT) approach to cable plough performance prediction based upon centrifuge model testing (2020)
Journal Article
Robinson, S., Brown, M., Matsui, H., Brennan, A., Augarde, C., Coombs, W., & Cortis, M. (2021). A cone penetration test (CPT) approach to cable plough performance prediction based upon centrifuge model testing. Canadian Geotechnical Journal, 58(10), 1466-1477. https://doi.org/10.1139/cgj-2020-0366

Cable ploughing is an important technique for burying and protecting offshore cables. The ability to predict the required tow force and plough performance is essential to allow vessel selection and project programming. Existing tow force models requi...

Effects of screw pile installation on installation requirements and in-service performance using the Discrete Element Method (2020)
Journal Article
Sharif, Y., Brown, M., Cerfontaine, B., Davidson, C., Ciantia, M., Knappett, J., …Ottolini, M. (2021). Effects of screw pile installation on installation requirements and in-service performance using the Discrete Element Method. Canadian Geotechnical Journal, 58(9), 1334-1350. https://doi.org/10.1139/cgj-2020-0241

Existing guidance on the installation of screw piles suggest that they should be installed in a pitch-matched manner to avoid disturbance to the soil which may have a detrimental effect on the in-service performance of the pile. Recent insights from... Read More about Effects of screw pile installation on installation requirements and in-service performance using the Discrete Element Method.

Physical modelling to demonstrate the feasibility of screw piles for offshore jacket supported wind energy structures (2020)
Journal Article

Screw piles potentially offer quieter installation and enhanced axial tensile capacity over straight-shafted driven piles. As such, they have been suggested as a possible foundation solution for offshore jacket supported wind turbines in deeper water...

This paper is devoted to the development of a stabilised implicit non-ordinary state-based peridynamics approach. We propose a geometrically nonlinear implicit approach focusing on quasi-static analyses. Since the construction of the Jacobian matrix...

Canadian Geotechnical Journal, 58(4), 565-582. https://doi.org/10.1139/cgj-2019-0548

Screw anchors have been recognised as an innovative solution to support offshore jacket structures and floating systems, due to their low noise installation and potential enhanced uplift capacity. Results published in the literature have shown that f...
