CFD-DEM simulation of slurry particle infiltration in granular soils
Get PDFOver recent decades, the slurry pressure balance (SPB) method has gained popularity due to its safety, efficiency, and environmental advantages, especially in undersea and river-crossing tunnels with high groundwater pressures. By employing a pressurised slurry, commonly a bentonite suspension, the stability of the excavation face is maintained. When the pressurised slurry infiltrates into the surrounding strata, its fine particles clog the soil pores and form a low-permeability filter cake at the excavation surface. The filter cake continuously transfers slurry pressure to balance soil and groundwater pressures, dynamically regenerating as tunnelling progresses and cutters disrupt it.
A variety of investigations have aimed to elucidate the underlying mechanisms of filter cake formation and infiltration. In particular, laboratory column tests have been widely used to characterise infiltration behaviour and filter cake properties. More recently, the coupled Computational Fluid Dynamics–Discrete Element Method (CFD–DEM) approach has proved effective in capturing the interactions between slurry particles and soil at the particle scale.
Despite these advances, numerical studies commonly simplify bentonite particles as spheres, overlooking their actual plate-like shape and potentially misrepresenting particle packing and permeability. Additionally, simplified infiltration models often neglect the dynamic, repeated infiltration and continuous filter cake reformation during tunnelling.
To address these gaps, this study models bentonite particles as oblate spheroids with varying aspect ratios and incorporates a simplified pitching torque model into the CFD–DEM framework to capture more realistic motion. Results show that higher aspect ratios improve infiltration channel sealing, enhancing slurry pressure transfer and excavation face stability.
Building on these developments, a more realistic SPB tunnelling model was developed to simulate infiltration under operational conditions. Coupled CFD–DEM simulations using this model and a standard column test enabled direct comparison. While both produced similar filter cakes, the SPB model showed greater infiltration distances, lower normalised permeability near the face, and faster fluid pressure dissipation—leading to quicker infiltration. These results highlight the dynamic model’s closer alignment with real tunnelling conditions, in contrast to the more conservative column test.
A new numerical framework was developed to simulate dynamic filter cake re-formation during tunnelling, incorporating multiple cycles of slurry re-infiltration and cutter head advancement. Compared to static models, the dynamic approach replicated field-observed pressure fluctuations. It also showed reduced infiltration rates, suggesting that static models may overestimate infiltration in such conditions.
Collectively, this study advances understanding of particle-scale slurry infiltration and dynamic filter cake evolution in SPB tunnelling. By incorporating realistic particle shapes, realistic tunnelling conditions, and repeated infiltration, it enhances the predictive accuracy and reliability of slurry shield tunnelling simulations

Kevin Fenton: A Reading
No full textThe John S. Lucas Great River Reading Series (GRRS) hosts Winona native and author Kevin Fenton. Fenton will read from his new novel Cyan Magenta Yellow Black published by Black Lawrence Press, 2025.
Kevin Fenton is the author of Merit Badges, which won the AWP Prize for the Novel and the Friends of the American Writers Award, and Leaving Rollingstone, which Patricia Hampl called “the most important memoir to come out of the Midwest (or anywhere) in years.” He works as an advertising writer and creative director; in that capacity, he’s published essays in the design quarterlies Émigré and Eye (London), the anthology Looking Closer 2: Critical Writing On Graphic Design, and the UX design blog Boxes and Arrows. He got a slightly better education than he deserved at Beloit College, the University of Minnesota Law School, and the University of Minnesota MFA program. He lives in St Paul with his wife Ellen and his greyhound Evie
'Web of Life' - Profile of Kevin Petrie in Printmaking Today Winter 2024
No full textKevin Petrie, Professor of Creative Practice at the University of Sunderland, uses print to explore the novels and philosophy of Iris Murdoch writes Dr Miles Leeson. This is a 1200 word profile of Kevin Petrie and his recent work for 'Printmaking Today' which is the journal of the Royal Society of Painter Printmakers. The piece gives an overview of Petrie's creative practice focusing on the novels and thinking of Dame Iris Murdoch (1919-1999). The piece discusses Petrie's evolving model of creative practice for this project: reading the novels, sketching to visualise elements, developing and combining images in the studio and then reengagement with Murdoch (through the community, literature and archive). Petrie's 'Other Journeys' and 'Web of Life' exhibitions are discussed.
The author, Dr Miles Leeson, is the Director of the Iris Murdoch Research Centre at University of Chichester and Visiting Research Fellow at Kingston University. He is the lead editor of the Iris Murdoch Review, the Series Editor of ‘Iris Murdoch Today’ with Palgrave Macmillan, and has published widely on Murdoch’s work. He published Iris Murdoch: Philosophical Novelist (Continuum) in 2010, the edited collection Incest in Contemporary Literature (Manchester University Press, 2018), the festschrift Iris Murdoch: A Centenary Celebration (Sabrestorm Fiction, 2019), the edited collection Iris Murdoch and the Literary Imagination (Palgrave Macmillan, 2022) and is currently writing Iris Murdoch: Feminist.
