Analysis on the excavation management system of slurry shield TBM in permeable sandy ground

Slurry shield TBMs with full-face mechanized excavation and active face support using slurry suspension are increasingly being employed for the construction of underwater tunnels. When tunneling in permeable sandy ground, the choice of suitable excavation management system and volume calculation method is extremely important to prevent security emergencies such as face collapse, water inflow and ground deformation. However, this subject has not...
