Comparison of Experimental and Theoretical Forces on a Model Dredge Cutterhead
… of a previously developed theory for estimating cutterhead forces. A MATLAB program is written and used to solve the theoretical equations. The sediment used in the study had a d50 of 0.27 mm and an angle of internal friction of 21.6?. The sediment is contained in the deep sediment pit 7.6 m (25 …

Examination of excavation chamber pressure behavior on a 17.5 m diameter earth pressure balance tunnel boring machine
… and key operating parameters such as thrust, cutterhead and screw conveyor torque, cutterhead and screw conveyor rotation speeds, etc., were studied in great detail to determine what parameters influenced chamber pressures and how. The results of detailed EPBM data analysis supported with …

Centrifuge modelling of the impact of mechanised tunnelling on piled foundations using a miniature TBM
… of real-life tunnelling machines including cutterhead overcut, shield tapering, and the use of a screw conveyor to extract soil from the excavation chamber in a controlled manner. The present mini-TBM can simulate the construction of a 4 m diameter prototype tunnel at 50g. Two centrifuge …

Foundation response to ground movements induced by tunnel excavation
… to simulate actual soil excavation by a rotating cutterhead and its effects on foundations in-flight, were reviewed and reproduced numerically. The continuum analyses predicted the settlement, differential settlement, bending moment and load redistribution of single piles and pile groups of …
