Post-Grouting of Drilled Shaft Tips on the Sutong Bridge: A Case History
The Sutong Bridge across the lower Yangtze River in China will have, when completed, the longest span (1,088 m) and the highest towers (306 m) of any cable stayed bridge in the world. The foundations for this record-setting span are drilled shafts under each of the main pylons. The North Pylon is supported on 131 drilled shafts, 2.5 m diameter and 114 m long. The South Pylon is supported on 131 drilled shafts 2.5 m in diameter and 117 m long. The tips of all drilled shafts were post-grouted after an extensive test program confirmed significant increase in capacity with post-grouting. This paper presents a description of the post-grouting test program, the results obtained, and the construction methods used for post grouting of the production drilled shafts.
