Investigation of the pressure distributions around quasi-rectangular shield tunnels in soft soils with a shallow overburden : a field study Universiteit Gent
The magnitudes and distributions of the pressures around a tunnel lining are the most significant variables in shield tunnel design, as they determine the safety of the lining structure and influence the investment cost of the tunnel project. The grouting process has a negligible effect on the pressures exerted on the shield tunnel segmental linings when the boring machine is drilling. However, improper grouting control might result in large ...
