摘要

In 2008, the Cobb County Water System began construction of the South Cobb Tunnel, its second wastewater tunnel. The South Cobb Tunnel is an 8.9-km (5.5-mile) long, 8.2-m (27-ft) diameter, hard rock tunnel. At its maximum depth of 122 m (400 ft), it is the deepest tunnel constructed in the Atlanta area. This paper describes ground and groundwater conditions encountered along the tunnel alignment, excavation using the refurbished Herrenknecht S-288 tunnel boring machine (TBM), excavation and concrete lining of the 34.7-m (114-ft) diameter pump station shaft and two 13.4-m (44-ft) diameter construction shafts, and construction of six tangential vortex intake structures that transfer flow from interceptor sewers to the tunnel.
