BLADE SHIELD TUNNELLING IN ESSEN

The article describes the excavation and lining of the fourth construction section of Essen's underground railway. The tunnel is located in an area of green sand and coarse silt in which the water table is located 5 M above the tunnel floor. As compressed air tunnelling methods could not be used because of thin cover and the soil structure, it was necessary to lower the water table by sinking wells. Tunnel excavation was performed with blade shield tunnelling equipment designed for use in unstable ground conditions. The article gives details of excavation methods used with this equipment in a built-up area and evaluates the resulting ground settlements.
